SUMMARY
A molecular substance consists of molecules that are identical, such as C4, which is a molecule formed by four carbon atoms bonded together. In contrast, a single carbon atom is classified as an element and not a molecular substance. According to Webster's definition, a molecule is the smallest unit of an element or compound, comprising one or more like atoms in an element and two or more different atoms in a compound. Therefore, while helium (He) is a molecule, sodium (Na) in its solid state is not classified as such due to its metallic bonding.
