In theoretical chemistry, the bonding orbital is used in molecular orbital theory to describe the attractive interactions between the atomic orbitals of two or more atoms in a molecule. In MO theory,

Atoms are the basic particles of the chemical elements and the fundamental building blocks of matter. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetica
