Question

How many electrons are transferred from Mg to nitrogen during formation of Mg3N2? Plz with equation.

Answer 1

when magnesium react with nitrogen then the nitrogen wants 3 electron but magnesium gives 2 electron but it is not a proper bonding so the proper balance chemical equation will:
3Mg +2N= Mg3N2

Answer 2

Answer:

        6 electrons from 3 Mg⁺² ions

Explanation:

Mg has two valence electrons in the outermost shells and Nitrogen contains 5 electrons in the outermost shell.

Nitrogen requires 3 electrons to complete its octet .  It gains 3 electrons to form N³⁻ . As a single Mg²⁺ ion can not donate the electrons to N atom . So, the compound Mg₃N₂ forms where 3Mg²⁺ ions donate electrons to 2N³⁻ ions. Thus completing the octet of both the atoms .
