Historical models of the atom

WebbThe modern Atomic Model was first developed by two key scientists Lavoisier and Dalton with the help of others. They formulated the key concepts of the law of conservation of mass and the existence of atoms as the building blocks of all matter using their knowledge of chemical reactions. WebbHistorical Models of the Atom. Leucippus' and Democritus' Atom Our English word “atom” comes from a Greek word “atomos” meaning the smallest unit of matter. Leucippus and Democritus, Greek philosophers of the late 5th century BC, taught that the smallest unit of matter, the atom, was irreducible and indestructible.
