Chemical Bonds

A bond is an electrostatic attraction between particles. They occur as elements try to achieve noble gas electron configuration. Keep in mind that noble gases have full valence electrons and do not form compounds because of their stability. Metals lose electrons, so they oxidize. Non-metals gain electrons, so they reduce.

There are two types of bonds: ionic and covalent. Ionic occurs when a metal losses electrons to a non-metal to achieve noble gas electron configuration. An example is potassium chloride, NaCl. Covalent bonding occurs between non-metals that share electrons to achieve stability. An example is water, H2O.
