The interatomic connection that comes from the sharing of an electron pair between two atoms is known as a covalent bond in chemistry. The electrical attraction of their nuclei to the identical electrons causes the binding. A covalent bond is formed when the total energy of the linked atoms is lower than that of widely spaced atoms.

Covalent Bond Definition
A covalent bond is established when the electrons from each participating atom are shared equally. A shared pair, or bonding pair, refers to the pair of electrons involved in this form of bonding. Molecular bonds are another name for covalent bonding. The atoms will acquire stability in their outer shell through the sharing of bonding pairs, analogous to noble gas atoms.
Multiple Bond
A multiple bond is a chemical bond between two atoms that share two or more electron pairs. Multiple bonds include:
- Double Covalent bond
- Triple Covalent Bond
Double bonds form when two atoms share two pairs of electrons, and triple bonds form when two atoms share three pairs of electrons.
Single bonds are stronger and shorter than double bonds, whereas triple bonds are the strongest and shortest covalent bonds.
A triple bond has six bonding electrons. The triple bond is represented by three parallel lines (≡). The most prevalent triple bond is found in acetylene. Triple bonds are more powerful than double or single ones.
