Vedclass · Answer

(B) The atomic number of nitrogen $(N)$ is $7$,which means a neutral nitrogen atom has $7$ electrons.For the $N^{3-}$ ion,it has gained $3$ electrons,so the total number of electrons in one $N^{3-}$ ion is $7 + 3 = 10$ electrons.One mole of $N^{3-}$ ions contains $6.022 	imes 10^{23}$ ions.Therefore,the total number of electrons in one mole of $N^{3-}$ ions is $10 	imes 6.022 	imes 10^{23} = 6.022 	imes 10^{24}$ electrons.

Calculate the number of electrons in one mole of $N^{3-}$ ion.
