Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

A molecule is a group of two or more atoms bonded together by covalent bonds.

A diatomic molecule consists of two atoms of the same or different elements, such as O2 or HCl.

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell.

A single covalent bond is formed when two atoms share one pair of electrons.

A double covalent bond is formed when two atoms share two pairs of electrons.
