Covalent Bond

Covalent bond

A covalent bond is a chemical bond based on the overlap of the electron orbits of two atoms.

When a covalent bond is formed, atoms exchange electrons to fill their outer electron shells. Electrons become common to both atoms.

A covalent bond can be single, double or triple. This depends on the number of pairs of electrons involved in the formation of the bond.

Covalent bonds are characteristic of compounds formed by non-metal atoms. It plays an important role in the creation of molecules of organic substances, including proteins and nucleic acids.

Covalent bonds provide molecules with a specific structure and shape. Thanks to it, the existence of complex chemical compounds on which life on Earth depends is possible.
