COVALENT chemical bonding is the process in which two atoms share a pair of valence electrons. As the binary opposite to ionic bonding, covalent bonding processes lead to stable molecules once they share electrons in a particular method to create a noble gas configuration for each atom. (HyperPhysics,2014) Using hydrogen as an example which forms the simplest covalent bond, two hydrogen atoms contain one valence electron each where in the structure of an atom the 1st shell contains two electrons. The two hydrogen molecules contain one valence electron each and once paired together in a covalent bonding process form a single atomic atom.

“METALLIC bonding is the strong attraction between closely packed positive metal ions and a sea of delocalized
