Answer :

(2) Dalton Explanation: Democritus first suggested the existence of the atom, but John Dalton (1766- 1844) is credited with the Atomic Theory of Matter. According to Dalton, all matter is made of atoms; atoms are indivisible and indestructible; all atoms of a given element are identical in mass and properties; and compounds are formed by a combination of two or more different kinds of atoms.
