Answer 1

Question :-

a) Explain the formation of Mg$_3$N$_2$ by the transfer of electrons.

Answer :-

Mg has 2 valence electrons and loses these 2 valence electrons to form Mg${}^{2 + }$ ion. N has 5 valence electrons. It gains 3 valence electrons to form N${}^{3 - }$ ion. To balance charges, 3 Mg${}^{2 + }$ ions combines with two N${}^{3 - }$ ions to form Mg$_3$N$_2$.

Question :-

b) Name the ions present in the compound.

Answer :-

Magnesium nitride ( Mg3N2 ) is an ionic compound of magnesium and nitrogen. Being an ionic compound, it contains two ions I.e. Mg${}^{ + 2 }$ and N${}^{ - 3}$.

Question :-

c) Write about the solubility of these compounds.

Answer :-

A white precipitate is formed when magnesium nitride is added to water. Therefore, magnesium nitride is soluble in water.
