Using electron-dot diagrams which show only the outermost shell electrons, show how a molecule of nitrogen, N₂, is formed from two nitrogen atoms. What name is given to this type of bonding?

As nitrogen has 5 electrons in its outermost shell so in order to fulfill its octet, it needs 3 more electrons. Therefore, it shares its 3 electrons with another nitrogen atom to form a molecule of nitrogen gas.

This type of bonding where the sharing of electrons takes place is called covalent bonding.
