Nanoscience and nanotechnology are the study of extremely small things and could be used across to many scientific fields like biology, physics and chemistry.
A polymer is a substance that has a molecular structure consisting mostly of large number of similar units bonded together. Generally a polymer is many synthetic organic materials used as plastics and resins.
A chemical compound is a chemical substance composed of atoms from more than one element held together by a chemical bond. All of the matter in the universe is composed of atoms of more than 100 different chemical elements found in pure form and combined. When new compounds form they have few, or sometimes even none, of the physical or chemical traits of the original elements, they have a new life on their own. There are millions of different compounds around you. Chemical changes in compounds happen when chemical bonds are created or destroyed.
Chemical bonds hold molecules together and create temporary connections that are essential to life. Common types of chemical bonds include covalent, ionic, and hydrogen bonds. Atoms tend to arrange themselves in the most stable pattern possible which means that they have a tendency to complete or fill their outermost electron orbits. The force that holds atoms together as molecules are referred to as a chemical bond.
