Antoine Lavoisier Discovers matter is made of atoms
Discovered atoms make up matter and matter cannot be created nor destroyed using his experiment of a diamond in ajar releasing gas and losing weight proving the atoms were transferring off of it. -
John Dalton discovers atoms have distinct masses and properties
Dalton discovered this by combining two masses of nitric acid with oxygen over water. He used the results of this experiment to show atoms are indestructible and have masses and properties. -
Max Planck
Discovered atoms can only emit small mounts of energy and named the quantum. -
Marie Curie
She proposed that radiation was atoms being disintegrated by the material. She found this through her experiment of a boiling mass with a heavy metal rod. -
Albert Einstein
Discovered special relativity by using moving trains and flashes of light. He also proved the existence of atoms through mathematics. -
Niels Bohr
Discovered that electrons orbit an atom in precise orbits.he discovered this through splitting an atom and doing nuclear fission. -
Werner Heisenberg
Heisenberg formulated quantum mechanics based a matrices. He also proposed the position of an electron using a gamma-ray microscope. -
Erwin Schrödinger
Schrödinger used a mathematical equation to describe the likelihood of electron positions in an atom. He used Schrödinger’s cat as a thought experiment.
