Magnesium nitride molar mass
The molar mass of magnesium nitride is 100.9494 g/mol.
Magnesium nitride color
Magnesium nitride is in greenish-yellow color.
Magnesium nitride viscosity
Viscosity is not applicable for magnesium nitride because of its high melting point.
Magnesium nitride molar density
The molar density of magnesium nitride is 0.0268mol/cm3. Molar density is reckoned by dividing the molar mass by density. So the molar density of magnesium nitride is 2.71/100.9494=0.0268 mol/cm3.
Magnesium nitride melting point
Magnesium nitride has the melting point of 15000 C. This elevated melting point is due to the crystalline form of magnesium nitride.so there exists strong attraction forces are present between the atoms.
Magnesium nitride boiling point
The boiling point is unworkable for magnesium nitride. But it can decompose at the temperature of 626°F.
Magnesium nitride state at room temperature
At room temperature, magnesium nitride exists as a white crystalline solid because its melting point is more than the room temperature.
Magnesium nitride ionic/covalent bond
The bond between magnesium and nitrogen in magnesium nitride is purely ionic because magnesium ion donates its three electrons to nitride ion, so bond formation takes.
Magnesium nitride ionic radius
The ionic radius for molecules is not molecules, but we can calculate the ionic radii of each atom separately. The ionic radii of magnesium and nitride ions are 66pm and 140pm.
Magnesium nitride electron configurations
According to Hund’s rule, the electron configuration is the filling of orbital electrons of an atom/molecule in its electronic shell. Let us see of Mg3N2 electronic configuration.
The electronic configuration of nitrogen and magnesium in magnesium nitride is [Ne]3S2 and 1S2 2S2 2P3. Each Magnesium ion has two valency electrons.
Magnesium nitride oxidation state
In magnesium nitride, the oxidation state of each magnesium is +2 because it donates its two outermost valency shell electrons to the nitrogen. Parallelly, nitrogen exhibits a -3 oxidation state because it accepts 3 electrons from magnesium.
Magnesium nitride acidity/alkaline
Magnesium nitride is acidic because its pH is between 5-7. The nitride ions pull the magnesium’s electron cloud, which makes the molecule accept the electrons.
Is magnesium nitride odorless?
Magnesium nitride is an odorless crystalline compound.
Is magnesium nitride paramagnetic?
Para magnetic character is shown by the molecules having unpaired electrons in their outermost valency shell. Let us see the magnetic character of magnesium nitride.
Magnesium nitride is a nonparamagnetic compound as it does not contain any unpaired electrons in its valency shell. Each magnesium ion donates its two unpaired electrons to the electrons deficiency nitride ion to make the bond with the nitride ion.
Magnesium nitride hydrates
Magnesium nitride is undetected in any hydrate form because of its high melting point.
Magnesium nitride crystal structure
The crystal structure of magnesium nitride is like corundum and crystallizes in space group cubic with crystal lattice parameters a=b=c= 10.02 Å and α=β=ɣ= 90.000.
Magnesium nitride polarity and conductivity
- Magnesium nitride is a polar molecule because magnesium ions donate their valency electrons to nitride ions to make the bond with it.
- Magnesium nitride has high thermal conductivity with a wide band gap of about 2.8 eV, and it is an optoelectronic material in the blue-violet wavelength range.
Magnesium nitride reaction with acid
Magnesium nitride reacts with metals like HCl and H2SO4 to form magnesium chlorides, ammonium sulfates, and magnesium nitrates.
Mg3N2 + 8HCl →3MgCl2 +2NH4Cl
Mg3N2 + 4H2SO4 →3MgSO4 + H8N2O4S
3Mg3N2 +28HNO3 →9Mg (NO3)2 +16NO +14H2O
Magnesium nitride reaction with base
