Answer:
Na₃N
Explanation:
The compound made by sodium and nitrogen is called sodium nitride.
The oxidation state of sodium is +1 it loses its one valance electron and get complete octet while nitrogen have five valance electrons it require three more electron to gain stability.
When it react with sodium it needed three electron that's why three sodium atom are react with one nitrogen atom to make the compound overall neutral.
Na⁺ N³⁻
Na₃⁺³N³⁻
Chemical equation:
6Na + N₂ → 2Na₃N
however this compound us unstable and decompose to gives nitrogen and sodium.
Chemical equation:
2Na₃N → 6Na + N₂
