Explanation:
Detailed explanation-1: -A molecule is a structure that consists of two or more atoms that are chemically bonded together. The structure might be an elemental or compound molecule. An elemental molecule contains only one type of atom, such as ozone (O3) or chlorine (Cl2). A compound molecule is made up of one or more different elements.
Detailed explanation-2: -A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. The shared electrons are attracted to the nuclei of both atoms. This forms a molecule consisting of two or more atoms. Covalent bonds form only between atoms of nonmetals.
