-
Laviosier
He provided the formula for the conservation of matter in chemical reactions. -
Coulomb
Formulated the Coulomb's law which talks about one of the main forces involved in atomic reactions. -
Dalton
He formed the atomic theory -
Michael Faraday
Discovered Electrolysis which is the splitting of atoms with electricity. -
Dmitri Mendeleeff
He discovered the periodic law which states that the properties of the elemnts are periodic functions of their atomic weights. -
G.J. Stoney
Discovered electricity were made of negativily charged particles called electrons. -
Wilhelm Roentgen
Discovered X-Rays -
Frederick Soddy
Discovered isotopes and half-life -
Hantaro Nagoaka
Depicted a model of the atom with flat rings of electrons revolvong around a positively charged particle. -
Heins Geiger
Invented a device to make noise when it located alpha particles. -
R.A. Millikan
He had an oil drop test that determined an electrons charge and mass. -
Ernest Rutherford
Discoverd using alpha particles as atomic bullets that the atoms nucleus is small, dense, and positively charged. And that electrons were outside of the nucleus. -
H.G.J. Moseley
He said that the atomic number of an element is equal to the number of protons in the nucleus. -
Niels Bohr
Discovered an explenation of the atomic structure. His atomic model had atoms built up of sucessive orbital shells of electrons. -
James Chadwick
He used alpha particles to discover a neutral atomic particle with a mass that is similar to a proton. That led to his discovery of the neutron.
