The correct Answer is:
To solve the question of how \( N_2 \) combines with metals to form compounds, we will follow these steps: ### Step 1: Understanding Metal-Nitrogen Compounds Nitrogen, in its diatomic form \( N_2 \), can react with certain metals to form metal nitrides. A nitride is a compound that contains nitrogen in the form of the nitride ion \( N^{3-} \). ### Step 2: Identifying the Reaction When a metal reacts with \( N_2 \), it typically forms a metal nitride. For example, magnesium reacts with nitrogen to form magnesium nitride. ### Step 3: Example Reaction Let's take magnesium as an example: - The reaction can be represented as: \[ 3Mg + N_2 \rightarrow Mg_3N_2 \] - Here, magnesium (Mg) has a +2 oxidation state, and the nitride ion \( N^{3-} \) has a -3 oxidation state. ### Step 4: Balancing the Reaction To balance the reaction: - We need 3 magnesium atoms to balance the 2 nitrogen atoms in \( N_2 \): \[ 3 \text{Mg} + \text{N}_2 \rightarrow \text{Mg}_3\text{N}_2 \] ### Step 5: Generalizing the Concept Other metals from Group 1 (like lithium) and Group 2 (like calcium) can also form nitrides: - Lithium can react with nitrogen to form lithium nitride \( Li_3N \). - Calcium can react with nitrogen to form calcium nitride \( Ca_3N_2 \). ### Conclusion Thus, \( N_2 \) combines with metals to form metal nitrides, such as magnesium nitride \( Mg_3N_2 \), lithium nitride \( Li_3N \), and calcium nitride \( Ca_3N_2 \). ---
