Answer:
Covalent bond (polar covalent bond) forms between oxygen and hydrogen in a single water molecule. Each oxygen molecule is bound to the hydrogen atom through the covalent bond.
Covalent bond: It is also known as a molecular bond, it is a chemical bond that shares the electron pairs between atoms. These electron pairs called bonding pairs and sharing pairs. The stable balance of attractive and repulsive forces present between atoms when they share their electrons is known as covalent bonding.
