A monomer is a small and simple molecule that acts as the basic unit to build larger polymers. These units join together through chemical reactions to form long and complex chains known as polymers.
During the polymerization process, monomers bond to each other repeatedly, creating a larger and more solid structure.
Monomers can be of different types, depending on the type of polymer they form, and their specific combination determines the properties and characteristics of the resulting polymer. Polymers are widely used in various materials and products, from plastics to proteins in living organisms.
