Chemical bond

A chemical bond is the phenomenon of atoms being held together in molecules or crystals. All chemical bonds are due to electrons interacting simultaneously with the atoms in question. These electrons are normally part of an atom's atomic orbital (AO), but in a bond, they thus form a molecular orbital (MO). These electron-nucleus interactions are caused by the fundamental force of electromagnetism. Atoms will form a bond if their orbitals become lower in energy when they interact with each other.
