-
He provided the formula for the conservation of matter in chemical reactions.
-
Formulated the Coulomb's law which talks about one of the main forces involved in atomic reactions.
-
He formed the atomic theory
-
Discovered Electrolysis which is the splitting of atoms with electricity.
-
He discovered the periodic law which states that the properties of the elemnts are periodic functions of their atomic weights.
-
Discovered electricity were made of negativily charged particles called electrons.
-
Discovered X-Rays
-
Discovered isotopes and half-life
-
Depicted a model of the atom with flat rings of electrons revolvong around a positively charged particle.
-
Invented a device to make noise when it located alpha particles.
-
He had an oil drop test that determined an electrons charge and mass.
-
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.
-
He said that the atomic number of an element is equal to the number of protons in the nucleus.
-
Discovered an explenation of the atomic structure. His atomic model had atoms built up of sucessive orbital shells of electrons.
-
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.
