This video is about the different ways that scientists have pictured the atoms over the years. It starts with Democritus and Leucippus, the first philosophers to discuss atoms. Then John Dalton did experiments on atomic theory. J.J. Thompson proposed the plum pudding model of the atom when he discovered electrons, and Ernest Rutherford countered with the nuclear atom when he discovered the nucleus in the gold foil experiment. Niels Bohr imagined that electrons circled the nucleus in orbits, and Erwin Schrodinger's quantum mechanical model pictures electrons buzzing around in orbitals.
