Rutherford's Experiment and The Structure of the Atom
Ernest Rutherford's (1871-1937) surprising discovery about the interior of the atom is most fundamental in explaining so many well-known phenomena. He took us from the plum pudding model to the planetary model of the atom we use today. More ...
Bohr's Explanation of the Hydrogen Spectrum
In 1915, Danish physicist Niels Bohr proposed that electrons orbit the nucleus of an atom at fixed energy levels, and that orbits further from the nucleus have higher energy levels. Electrons emit energy in the form of light when they return to a lower energy level. More ...
