A molecule is defined as 2 or more atoms chemically bound together, consisting of one or more chemical element[1]. Using Atomic Force Microscopy (AFM) the chemical structure of the molecules can be seen in high definition at room temperature[2]. Molecules that are linked to the same molecule forming a chain creates a polymer, the molecules that are linked together are defined as a monomer[3].
