Bond types

Three types of bonds

An ionic bond is the bonding between a non-metal and a metal, that occurs when charged atoms (ions) attract after one loses one or more of its electrons, and gives it to the other molecule, for example sodium and chlorine


A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.


The chemical bond characteristic of metals, in which mobile valence electrons are shared among atoms in a usually stable crystalline structure.

negatively charged electrons (e) move freely around positively charged silver ions (Ag), bonding the atoms together
