Detailed explanation-1: -When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound.

Detailed explanation-2: -The atoms in most molecules are held together by strong attractive forces called chemical bonds. These bonds are formed through the interaction of valence electrons of the combining atoms. In addition to the very strong forces within a molecule, there are weaker forces acting between molecules.

Detailed explanation-3: -A molecule is a group of atoms bonded together.
