B. Covalent bond

The chemical bond formed by sharing of two valence electrons between two atoms is called a covalent bond. e.g., Covalent bond is formed between oxygen and each of the hydrogen in a water molecule (H2O). Each of the covalent bonds contains two electrons – one from a hydrogen atom and one from the oxygen atom. Both atoms share the electrons. Signup and view all the answers
