Question

Name two metals that directly combine with nitrogen on heating.

Answer 1

Nitrogen:

• It is a Chemical element with symbol $N$ .
• It is a non-metal.

Metal:

• Metals are good conductors of heat and electricity.
• All of the metals are solids at room temperature except mercury, which is a liquid.

Examples of Metal: Iron, Aluminum, Gold, Lithium, Magnesium

Lithium and Magnesium are two metals that directly combine with nitrogen on heating.

The reaction between Lithium and Nitrogen gas:

• When Lithium reacts with Nitrogen gas on heating Lithium nitride is formed.
  $$\begin{gathered} 6\mathrm{Li}\left(\mathrm{s}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)\stackrel{∆}{\to }2{\mathrm{Li}}_3\mathrm{N}\left(\mathrm{s}\right) \\ (\mathrm{Lithum}\mathrm{nitride}) \end{gathered}$$

The reaction between Magnesium and Nitrogen gas:

• When Magnesium reacts with Nitrogen gas on heating magnesium nitride is formed.
  $$\begin{gathered} 3\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)\stackrel{∆}{\to }{\mathrm{Mg}}_3{\mathrm{N}}_2\left(\mathrm{s}\right) \\ \mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}\mathit{}(\mathrm{magnesium}\mathrm{nitride})\mathit{} \end{gathered}$$

Therefore, Lithium and Magnesium are two metals that directly combine with nitrogen on heating.
