Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.he covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the sharing is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions. Each atom consists of protons, neutrons and electrons.
