All bodies are made up of atoms (tiny invisible particles)The electron is discovered by J. J. ThomsonGold Foil experiment leads to discovery of the nucleus by Ernest RutherfordAntoine Lavoisier discovers that mass is conserved in chemical reactions.J.J Thomson
Discovered the electronCathode Ray Tube experiment: JJ Thomson
fist subatomic particles. Different metals releases cathode raysJohn Dalton: all matter are made of atomsDaltons Atomic Theory:experiment with gases created a modern theory of n atomGold Foil Experiment: Ernest Rutherford
nuclear theory of the atom with alpha particles and gold foilPlum Pudding Atomic Model: JJ thomson atoms are surrounded by electronsRobert Millikan : hleped dicover the charge of an elcetronOil Drop Experiment: Robert Millikan
helps measure an electron charge. With droplets of oil and metal.Law of Conservation and Mass: Antonie Lavoisier
mass is neither created nor destroyed by chemical reactions or physical transformationsAntoine Lavoisier: mass is consereved in a chemical reactionJames Chadwick: discoved the neutronErwin Schrodinger: discovered the electron using a mechanical model atomNeils Bohr : Created the Bohr Model with Ernest RuthfordBohr Plantary Model: Neils Bohr and Ernest Rutherford
The atom is a positively charged nucleusRutherford Model: Ernest Rutherford JJ Thomsonś model was incorrect. Rutherford made a modern modelErnes Rutherford: Discorved the Rutherford model
