The answer is C!!!!!!!!!!!!!!!!!!!
Answer:
3 electrons are gained by one nitrogen atom in the formation of K₃N.
Explanation:
The reaction is as follow,
<span> 6 K + N</span>₂<span> </span>→ <span> 2 K</span>₃<span>N
</span>
Oxidation of K,
K → K⁺ + 1 e⁻
Or,
6 K → 6 K⁺ + 6 e⁻
In oxidation reaction potassium atom transfers one electron per atomn and six electrons per six atoms.
Reduction of N;
N₂ + 6 e⁻ → 2 N³⁻
In reduction reaction one molecule of N₂ gains six electrons and 3 electrons per one atom
