How is your body similar to the chair you are sitting in? Both things are made up of atoms! In fact, almost everything in the entire universe is made up of atoms. They are the building blocks of matter.
In fifth century BC, the Greek philosopher Leucippus and his student Democritus were the first people to suggest the idea of atoms. Most of Greek society believed matter was made up of earth, fire, water and air. This belief was so popular it perpetuated for the next two thousand years. But between the 17th and 19th centuries, Irish scientist Robert Boyle and English scientist John Dalton developed atomic theory. Boyle referred to simple substances made up from atoms as “elements”. Dalton said there were a limited number of types of atom and that matter was made up of a combination of these atom types. From the work of Boyle and Dalton, atomic theory became an important part of chemistry.
