Detailed explanation-2: -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.
