Lithium belongs to Group I of the Periodic Table. Nitrogen belongs to Group V of the Periodic Table. When lithium reacts with nitrogen, the ionic compound lithium nitride is formed. What happens to the electrons when lithium atoms and nitrogen atoms form ions?
- Aeach lithium atom loses one electron to form a $\text{Li}^+$ ion; each nitrogen atom gains three electrons to form an $\text{N}^{3-}$ ion
- Beach lithium atom loses one electron to form a $\text{Li}^+$ ion; each nitrogen atom gains five electrons to form an $\text{N}^{5-}$ ion
- Ceach lithium atom gains one electron to form a $\text{Li}^-$ ion; each nitrogen atom loses three electrons to form an $\text{N}^{3+}$ ion
- Deach lithium atom gains one electron to form a $\text{Li}^-$ ion; each nitrogen atom loses five electrons to form an $\text{N}^{5+}$ ion
