Final answer:
A triple covalent bond is formed by sharing three pairs of electrons between atoms. Nitrogen atoms in N₂ form a diatomic molecule with a triple bond, which means each atom shares three electron pairs.
Step-by-step explanation:
A triple covalent bond is a covalent bond formed by atoms that share three pairs of electrons. The element nitrogen is a gas that composes the majority of Earth's atmosphere. A nitrogen atom has five valence electrons, which can be shown as one pair and three single electrons. When combining with another nitrogen atom to form a diatomic molecule, the three single electrons on each atom combine to form three shared pairs of electrons.
