Chemical bond

A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic forces.

In general, strong chemical bonds are found in molecules, crystals or in solid metal and they organize the atoms in ordered structures.

Weak chemical bonds are classically explained to be effects of polarity, or the lack of it, of strong bonds.
