Silver is a white coloured lustrous latest discuss about various facts about silver in this article.
Silver is an important element with various properties. It has high thermal and electrical conductivity with good crystal size is fcc with 144 pm atomic radius. It is a very good ductile and malleable metal which is used as a disinfectant in some cases.
Silver is unreactive in nature due to the poor shielding of electrons present in the 4d subshell. Let us discuss about properties like atomic weight, covalent radius,melting point of Silver in the following sections.
Silver Symbol
The chemical symbol of Silver is Ag. This symbol comes from a Latin word argentum meaning “shiny “or “white”.

Silver electronegativity according to Pauling
The electronegativity of silver as 1.93. The electron attracting ability of silver is low as compared to fluorine.
Silver atomic density
The atomic density of Silver is found to be 10.49g/cm3 .
Silver melting point
The melting point of silver is 1234.93 Kelvin or 961.78 degree Celsius. From this we can understand thermal resistivity of silver.
Silver boiling point
The boiling point of silver is 2435 Kelvin or 2162 degree Celsius . silver is able to withstand at very high temperature.
Silver Vanderwaals Radius
The vanderwaals radius of silver is found to be 172 pm. Vanderwaals force is one of the weakest force which held in between bonds.
Silver ionic or covalent radius
The covalent radius of Silver is 145pm. This value can be increased or decreased by 5pm.
Silver isotopes
Isotopes is denoted by the chemical symbol of element with atomic number as subscript and mass number as superscript . Let us see whether Silver have isotope or not.
There are seven isotopes seen for silver. In which two were naturally found and the rest is synthetic isotopes. The below table depicts all the isotopes of silver.
| Isotopes | Abundance |
|---|---|
| 105Ag | syn |
| 106Ag | syn |
| 107Ag | 51.839% |
| 108Ag | syn |
| 109Ag | 48.161% |
| 110Ag | syn |
| 111Ag | syn |
Silver electronic shells
The first electronic shell K has the ability to hold only two electrons . Let us discuss about the electronic shell of silver.
The electronic shell arrangement of Silver is 2,8,18,18,1. All the first four shells are fully filled.
Silver energy of first ionization
The energy of first ionization of Silver is 731KJ/mol. Here needs only little energy to eject the loosely held electron from the outer compared with the inner shells.
Silver energy of second ionization
The second energy of ionization of Silver is 2070 KJ/mol. There needs very huge energy to remove the next electron from a monopositive silver atom.
Silver energy of third ionization
Silver third ionization energy is 3361KJ/mol. This is more than the second ionization energy of silver.
Silver oxidation state
The oxidation state of Silver is -2 ,- 1,0, + 1,+ 2, + 3. This means silver can withdraw one to three electrons and can accept two to one electrons.
Silver electron configuration
The electronic configuration of Silver is 4d10 5s1.
Silver CAS number
The CAS Number of Silver is 7440-22-4.
Silver ChemSpider ID
The chemspider ID of Silver is 22394
Silver Allotropic Forms
Allotropy is a special case of polymorphism where an element can exist in more than one form. Let us check whether Silver has allotropes or not.
There is no specific form or allotrope is found for silver. But certain studies shows it exhibits polymorphism. It can form three forms.
In which one is soluble in water which turns insoluble in water and other has gold like lustre and color. All has hexagonal like structure.
Silver chemical classification
Silver is a d block element which belongs to period five and group eleven of periodic table. It is a transition metal having excellent properties which makes them to be utilised for various purposes in different fields.
Silver State at room temperature
Silver is solid at room temperature.
Is Silver Paramagnetic?
Paramagnetic materials exhibits electron spin in same direction for the unpaired electron. Let us look whether Silver is Paramagnetic or not.
Silver is a paramagnetic element. It is because of one unpaired electron in it. It’s electronic configuration is 4d10 5s1. There is one unpaired electron in s orbital makes the element paramagnetic.
But when one of the electron is lost then silver turns to Ag that has diamagnetic character due to paired electrons.
Conclusion
Silver can form oxides,halides,sulphide and some organometallic compounds at very low temperature. The heat of fusion of silver is 11.28 kJ/mol. The minerals of silver as argentite and chlorargyrite. In most of the case it is formed as a by product of Cu,Au,Pb and Zn refining.
