Mc or Moscovium is a synthetic post-transition metal element, extremely radioactive in nature with a very short half-life. Let us explain Moscovium in detail.
Mc is transactinide element belong to the pnictogen group of 15. It has quite similar properties with lighter congeners like Nitrogen, and phosphorus. It comes under super heavy elements as it has greater than 103 atomic numbers.
Mc has significant similarities with thallium as both have loosely bound electrons. Let us discuss some of the chemical properties of Moscovium like melting point, boiling point, atomic number, etc. in this article.
1. Moscovium symbol
Symbols are used to express the element by using one or two letters of the English or Latin alphabet of the chemical name. Let us predict the atomic symbol of Moscovium.
The atomic symbol of Moscovium is “Mc”.
2. Moscovium group in the periodic table
Vertical lines or columns in the periodic table are referred to as respective group of the periodic table. Let us predict the group of Moscovium in the periodic table.
The group of Moscovium in the periodic table is 15 because it is a pnictogen metal. So, it is placed in the 15th group as an element. In the Mendeleev periodic table, it is group 15 but in the modern table, it is placed as the VA group as per the precipitation table.
3 Moscovium period in the periodic table
A horizontal line or row of the periodic table where every element is placed by its last principle quantum number is called a period. Let us predict the period of Moscovium.
Moscovium belongs to period 7 in the periodic table because it has more than 86 electrons in the valence shell. Up to period 6, there will be 86th elements that are well placed, so the remaining 29 electrons get 7th period and 15th group after the actinide series along with the post-transition element.
4. Moscovium block in the periodic table
The orbital where the valence electrons of the element are present is called the block of the periodic table. Let us predict the block of Moscovium.
Moscovium is a p-block element because the valence electrons are present in the p orbital. Mc also has s, d, and f orbitals but the outermost electrons are present in the 7p orbital according to the Aufbau principle.
5. Moscovium atomic number
The value of Z, known as the atomic number, is the total number of electrons. Let us find the atomic number of Moscovium.
The atomic number of Moscovium is 115, which means it has 115 protons because the number of protons is always equal to the number of electrons. For this reason, they become neutral due to the neutralization of equal and opposite charges.
6. Moscovium atomic Weight
The mass of the element is called weight which is measured concerning some standard value. Let us calculate the atomic weight of Moscovium.
The atomic weight of Moscovium is 288 on the 12C scale which means the weight of Moscovium is the 288/12th part of the weight of the carbon element. The original atomic weight of Moscovium is 289, it is because the atomic weight is the average weight of all the isotopes of the element.
7. Moscovium Electronegativity according to Pauling
Pauling electronegativity is the power to attract any other element for that particular atom. Let us predict the electronegativity of Moscovium.
The electronegativity of Moscovium is 7 according to the Pauling scale, which means it has electropositive nature and can attract electrons toward itself. The most electronegative atom as per the Pauling scale in the periodic table is fluorine having 4.0 electronegativity.
8. Moscovium atomic Density
The number of atoms present per unit volume of any atom is called the atomic density of that respective element. Let us calculate the atomic density of Moscovium.
The atomic density of Moscovium is 13.5 g/cm3 which can be calculated by diving the mass of Moscovium with its volume. Atomic density means the number of atoms present per unit volume but the atomic number is the number of electrons present in the valence and inner orbital.
- Density is calculated by the formula, atomic density = atomic mass / atomic volume.
- The atomic mass or weight of Moscovium is 289 g
- The volume of the Moscovium molecule is 22.4 liter at STP as per Avogardo’s calculation
- So, the atomic density of Moscovium is, 289/ (22.4) = 12.90 g/cm3
9. Moscovium melting point
Changing to a liquid state from its solid state at a particular temperature is called the melting point of that particular element. Let us find the melting point of Moscovium.
The melting point of Moscovium is 4000 C or 673 K temperature because at room temperature Moscovium exists as a solid and is radioactive. It needs less energy to melt the crystal into a liquid. By increasing the temperature, the elements can be placed in good arrangement.
10. Moscovium boiling point
The boiling point is the point when the vapor pressure of an element becomes equal to its atmospheric pressure. Let us find the boiling point of Moscovium.
The boiling point of Moscovium is 11000 C or 1373K because it exists in solid form at room temperature and also it is a post-transition metal element.
11. Moscovium Van der Waals radius
Van der Waal’s radius is the imaginary measurement between two atoms where they are not bound ionically or covalently. Let us find Van der Waal’s radius of Moscovium.
The Van der Waal’s radius of Moscovium is 187 pm because Mc has 6s and a filled 4d, 4f orbital so it has a very poor screening effect. For this reason, the nucleus attraction force for the outermost orbital increases, and this decreases radius.
- Van der Waal’s radius is calculated by the mathematical formula considering the distance between two atoms, where atoms are spherical in shape.
- Van der Waal’s radius is, Rv = dA-A / 2
- Where RV stands for Van Waal’s radius of the molecule of spherical shape
- dA-A is the distance between two adjacent spheres of the atomic molecule or the summation of a radius of two atoms.
12. Moscovium ionic radius
The summation of cation and anion is called the ionic radius of the element. Let us find the ionic radius of Moscovium.
The ionic radius of Moscovium is 187 pm which is the same as the covalent radius because for Moscovium the cation and anion are the same and it is not an ionic molecule. Rather, it forms by the covalent interaction between two Moscovium atoms.
13. Moscovium isotopes
Elements having the same number of electrons but different mass numbers are called isotopes of the original element. Let us discuss the isotopes of Moscovium.
Moscovium has 5 isotopes based on their neutron number which are listed below:
- 286Mc
- 287Mc
- 288Mc
- 289Mc
- 290Mc
Stable isotopes are discussed in the below section of Moscovium:
| Isotope | Natural Abundance | Half-life | Emitting particles | No. of Neutron |
| 286Mc | Synthetic | 20 ms | α | 171 |
| 287Mc | Synthetic | 37 ms | α | 172 |
| 288Mc | Synthetic | 164 ms | α | 173 |
| 289Mc | Synthetic | 330 ms | α | 174 |
| 290Mc | Synthetic | 650 ms | α | 175 |
Mc itself is highly radioactive in nature so its isotopes are also heavily radioactive and can emit radioactive particles all the isotopes are very reactive and have less stability.
14. Moscovium electronic shell
The shell surrounding the nucleus as per principal quantum number and holding the electrons is called an electronic shell. Let us discuss the electronic shell of Moscovium.
The electronic shell distribution of Moscovium is 2 8 18 32 32 18 5 because it has s, p, d, and f orbitals around the nucleus. Since it has more than 86 electrons and to arrange 115 electrons, it needs 1s,2s,2p,3s,3p,3d,4s,4p,4d,4f,5s,5p,5d,5f,6s,6p,6d7s,and 7p and orbitals.
15. Moscovium electron configurations
The electronic configuration is an arrangement of the electrons in available orbital by considering Hund’s rule. Let us discuss the electronic configuration of the Moscovium.
The electronic configuration of Moscovium is 1s22s22p63s23p6 3d104s24p64d104f145s25p65d10 5f14 6s26p66d107s27p3 because it has 115 electrons and those electrons should be placed to the nearest orbital of the nucleus s, p, d, and f orbitals and for the 1st,2nd, 3rd, 4th,5th, 6th, and 7th orbitals.
- Due to exchange energy, electrons enter first in 7s orbital then 6d.
- Where the first number stands for the principal quantum number
- The letter is for orbital and the suffix number is the number of electrons.
- But many elements have more principal quantum numbers depending on the number of electrons.
- Rn has 86 electrons, so the remaining electrons are present after the noble gas configuration.
- So, it is denoted as [Rn]5f146d107s27p3.
16. Moscovium energy of first ionization
First I.E. is the energy required for the removal of an electron from the valence orbital of its zero oxidation state. Let us predict the first ionization of Moscovium.
The first ionization value for Mc is 538.3 KJ/mol because the electron was removed from the half-filled 7p orbital. Due to the relativistic effect of 7s orbital, it requires more energy to remove the electron, and also electron removal from 7p is the unfavorable process as the half-filled stabilization is lost.
17. Moscovium energy of second ionization
The second I.E. is the energy required for the removal of one electron from the available orbital from the +1 oxidation state. Let us see the second ionization energy of Moscovium.
The 2nd ionization energy of Moscovium is 1760 KJ/mol because, in the 2nd ionization, electrons are removed from the 7p orbital. When an electron is removed from a half-filled orbital, it needs more energy, and also +1 is the stable state for Mc. Therefore, the 2nd ionization energy is very high than 1st.
18. Moscovium energy of third ionization
Removal of the third electron from the outermost or pre-ultimate orbital of an element having a +2 oxidation state is the third I.E. Let us predict the third I.E. of Moscovium.
The third ionization energy for Mc is 2650 KJ/mol because the third ionization occurs from 7p orbital and gets stabilization but the value is higher than expected because
- Mc has a 7s orbital which is subject to relativistic contraction and for this, the nucleus attraction for the outer electrons will be increases
- Mc has also 5f and 6d orbital which is subject to poor shielding effect and for this reason also nucleus attraction force on the outer electrons will be increased and the removal of the electron required a larger amount of energy.
19. Moscovium oxidation states
During bond formation, the charge that appears on the element is called the oxidation state. Let us predict the oxidation state of Moscovium.
Mc has +1 and +3 oxidation states, although it belongs to group 15. Due to the inert pair effect, the electrons try to stay in the 7s orbital as paired form, so it cannot show pentavalent nature but rather shows trivalent nature like nitrogen.
20. Moscovium CAS number
CAS number or CAS registration for any element is used to identify the unique element. Let us know the CAS number of the Moscovium.
The CAS number of the Moscovium molecule is 54085-64-2, which is given by the chemical abstracts service.
21. Moscovium Chem Spider ID
Chem Spider ID is the particular number given to a particular element by the Royal Society of Science to identify its character. Let us discuss it for Moscovium.
The Chem Spider ID for Moscovium is 4565221. By using this number, we can evaluate all the chemical data related to Moscovium atom.
22. Moscovium allotropic forms
Allotropes are elements or molecules with similar chemical properties but different physical properties. Let us discuss the allotropic form of Moscovium.
Moscovium has no allotropic forms because it does not show catenation properties like carbon rather it shows an inert pair effect.
23. Moscovium chemical classification
Based on the chemical reactivity and nature, the elements are classified into some special class. Let us know the chemical classification of Moscovium.
Moscovium is classified into the following categories:
- Mc is a post-transition pnictogen metal element
- Mc is a super heavy element
- Mc is a transactinide metal
- Mc is a strong radioactive synthetic element
24. Moscovium state at room temperature
The physical state of an atom is the state at which an element exists at room temperature and standard pressure. Let us predict the state of Ba at room temperature.
Moscovium exists in a solid state at room temperature because it has higher Van der Waal interaction. In the crystal form, it adopts rhombohedral geometry so the atoms exist very close to each other. The randomness of the atom is very high at room temperature.
The solid-state of Moscovium can be changed to liquid at a very low temperature, where the randomness will be decreased for Moscovium atom.
25. Is Moscovium paramagnetic?
Paramagnetism is the tendency of magnetization in the direction of the magnetic field. Let us see whether Moscovium is paramagnetic or not.
Moscovium is paramagnetic due to the presence of three unpaired electrons in the valence 7p orbital.
Conclusion
Moscovium is a post-transition pnictogen metal element, due to its strong radioactive nature it cannot be used the normally like other elements. It has electrons loosely bound to its quasi-closed shell so it can donate electrons easily.
