Atoms are small tiny particle of an element. The word Atom has derived from Greek word which means “Indivisible”. Greeks assumed that matter consists of tiny particles which could not be divided further and it was a sort of philosophical idea with no scientific support.
An English Chemist and Mathematician – John Dalton was the first person to scientifically prove that matter consists of indivisible discrete particles. Dalton developed an atomic theory in 1803. Subsequently, Ernest Rutherford, a famous scientist of Briton developed a modern concept of the atomic structure. He stated that an Atom is composed of heavy nucleus in the center with a positive charge of electricity and negatively charged electrons surrounding it.
