What are chemical bonds

A force resulting from the redistribution of energy contained by orbiting electrons, which tends to bind atoms together to form molecules. A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds.

Bonds between to elements. They can consist of an ionic bond (metal and nonmetal), a covalent bond (2 non metals) or a metallic bond (2 metals)
