Said that all matter is composed of indivisible elements.
-
A British Chemist who said that matter is composed of atoms of different weights. Also said that atoms are spherical in shape and move around.
-
He discovered electrons by using properties of cathode rays.
-
He is widely known as the father of Nuclear Physics. He developed the theory for the structure of the atom by conducting his Gold Foil Experiment. He observed the way alpha particles scattered and demonstrated for the first time the existence of the atomic nucleus.
-
He developed the Bohr atomic model. This showed electrons orbiting the nucleus, and chemical properties being determined by how many electrons are in the outer orbits.
-
They described how electrons move in wave the form of waves and developed the Schrodinger equation which describes how the quantum state of a system changes with time.
