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 pure substance whose molecules contain two or more atoms, combined together in a definite ratio is called compound.

Detailed explanation-3: -A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.

Detailed explanation-4: -A substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule is known as compound.

Detailed explanation-5: -Diatomic molecules are when only two atoms combine. An example of a diatomic molecule is carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called a homonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).
