The physical properties of molecular substances Molecules are made of fixed numbers of atoms joined together by covalent bonds, and can range from the very small (even down to single atoms, as in the noble gases) to the very large (as in polymers, proteins or even DNA).olecular substances tend to be gases, liquids or low melting point solids, because the intermolecular forces of attraction are comparatively weak. You don't have to break any covalent bonds in order to melt or boil a molecular substance.
What is the smallest unit of a substance that exhibits the properties of that substance? A molecule of the substance. An atom of an element may exhibit different characteristics when it is bound to other atoms of the same element. Examples are common oxygen (Oâ¦2) and ozone (O3) with altered chemical properties.
