Vedclass · Answer

(A) The atomic number $(Z)$ of nitrogen is $7$,which represents the number of protons.In a neutral nitrogen atom,the number of electrons is equal to the number of protons,which is $7$.When a nitrogen atom forms a nitride ion $(N^{3-})$,it gains $3$ electrons.Therefore,the number of electrons in $N^{3-} = 7 + 3 = 10$.The number of protons remains unchanged at $7$.Thus,the nitride ion has $7$ protons and $10$ electrons.

The nitrogen atom has $7$ protons and $7$ electrons. The nitride ion $(N^{3-})$ will have:
