Chemical Bonding and Molecular Structure 3 | P a g e reaction with oppositely charged ions. For example, • Covalent Bond—Lewis-Langmuir Concept When the bond is formed between two or more atoms by mutual contribution and sharing of electrons, it is known as covalent bond. If the combining atoms are same the covalent molecule is known as homoatomic. If they are different, they are known as heteroatomic molecule. For Example,
