Lavoisier's Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. This law helped future scientists in the development of the atom.

-
Dalton proposed the first ever model of the atom. He stated that atoms were tiny, invisible particles. Each atom has a certain mass, size, and chemical behavior.
-
Prousts' Law of Definite Proportions states that a chemical compound always contains exactly the same proportion of elements by mass.
-
Kelvin proposed a theory that atoms were shaped like vortices spiralling around each other. Kelvins theory lead to the development of other theorys in the development of the atom.
-
Thomson conducted the Cathode Ray tube Experiment to make his Plum Pudding Model, which shows the atom (pudding) with scattered electrons in it (plums).
-
Geiger was Rutherfords assistant in the Gold Foil Experiment which led to the discovery of the nucleus and the Nuclear Model.
-
Rutherfords Gold Foil Experiment led to his proposing his theory of a nucleus. This later lead to his own atomic mddel, the Nuclear Model.
-
Neils Bohr depicted the atom as a small, positively charged nucleus surrounded by electrons that travel in orbits thus creating his model of the atom
-
Rutherford postulated hydrogen nuclei tobe a new particle, called the proton
-
Erwin Schrodinger used mathematical equations to describe the likelyhood of finding an electron in a certain position. Using this, Schrodinger created the Quantum mechanical model of the atom using the quantum theory.
-
Pauli used Heisenberg's theory to derive the observed spectrum of the Hydrogen atom. Pauli's work helped to credify Heisenberg's theory.
-
Heisenberg's Uncertainty Principle states that the more precisely the position is determined, the less precisely the momentum is known in this instant and vice versa.
-
Chadwick used scattered data to calculate the mass of this neutral particle.
