When does the bond formation between two atoms occur?

Chemical bonds:

• A chemical bond is a bond formed between two atoms.
• There are different types of bonds depending on the electrons shared between the atoms.
• They are ionic, covalent, coordination bonds, hydrogen bonds etc.

Bond formation:

• The formation of bonds is accompanied by a decrease in the system's energy.
• The bond is formed when the electrons are shared between the two or more atoms.
• When the atomic orbitals overlap it results in the formation of a bond.
• More the overlap of atomic orbitals, the stronger the bond.
• Because of the bonding to the surface, new electronic states are produced when an atom or molecule is adsorbed on a surface.
