Text Solution

Verified by Experts

The chemical bond formed by sharing of two valence electrons between the two atoms is called covalent bond. e.g. Covalent bond is formed between oxygen and each of the hydrogen in a water molecule `(H_2O).`
Each of the covalent bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms share the electrons. `H:underset (* *)overset(* *)O:H`
