Chemistry is often considered the connecting science that relates all other scientific disciplines to each other. This is as it is mainly concerned with the energy that holds matter together. Matter is the major topic of study in chemistry as chemists study its transformations and interactions. They study atoms as well as collections of atoms like molecules and crystals that compose matter. Chemistry is a fairly modern science but owes its roots to the early science of alchemy.
