Chemistry is the science and study of matter, including its properties, composition as well as reactivity. Chemistry relates to everything that can be sensed from minute elements to complex structures. The atom and molecules are the basic unit or components of Chemistry. The study of chemists is always interested in identifying and knowing how chemical transformation occurs. It plays an essential role in science and plays a central role in daily life activities.
