The bond that holds the two nitrogen atoms together in nitrogen gas (N₂) is a triple covalent bond.

Here's why:

* Covalent bond: Nitrogen atoms share electrons to achieve a stable electron configuration.

* Triple bond: Each nitrogen atom contributes three electrons to the bond, resulting in a total of six shared electrons. This is represented by three lines in the Lewis structure (N≡N).

This triple bond is very strong, making nitrogen gas very stable and unreactive at room temperature.
