Detailed explanation-1: -When there is sharing of electrons between two atoms, they are bonded together by that sharing. These bonds are called covalent bonds. So, A group of atoms held together by chemical bonds is molecules.

Detailed explanation-2: -A molecule is a neutral group of atoms joined by covalent bonds.

Detailed explanation-3: -A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have low melting and boiling points, and do not conduct electricity.

Detailed explanation-4: -A covalent bond involves the mutual sharing of electrons between the atoms resulting in the formation of a molecule. Thus, they are also termed molecular bonds.

Detailed explanation-5: -A substance with small molecules has strong covalent bonds that hold the atoms together in its molecules . There are weak forces between molecules and their neighbours. The structure and bonding of substances with small molecules explains their properties .
