John Dalton
He was a British chemist who created a theory in which matter is composed of atoms of different weights and combined in ratios by weight. -
Dalton´s model
Dalton advanced atomic theory was by saying we had many different atoms out there. His model, often dubbed the "billiard ball" model, basically says you can't divide the atom into smaller pieces. -
William Crookes
He constructed a primitive cathode ray tube, which today is the reason why we have television -
JJ Thomson
He discovered the electron, using properties of cathode rays. -
The plum pudding model
Thomson's plum pudding model is the model of an atom where an atom is regarded as a sphere positively charged matter in which electrons were embedded. -
Ernest Rutherford
He was known as the father of nuclear physics. He also developed the theory for the structure of the atom. -
Rutherford Model
Rutherford demonstrated for the first time the existence of the atomic nucleus. He used a gold foil experiment, observing the scattering of alpha particles. -
Neils Bohr
Known for the Bohr´s model -
Bohr atomic model
Bohr atomic model meant electrons travelling in orbits around the nucleus, and the chemical properties are determined by the quantative of electrons are in the outer orbits. -
James Chadwick
He discoverd the neutron component of the atomic nucleus, where he explained the nuclear fission of uranium 235. This made possible to produce elements heavier than uranium in the lab. -
Quantum Mechanical Model
Erwin Schrodinger invented the Quantum Mechanical Model. It's based on quantum mechanics, used to find the probable position and location of an electron in an atom. -
