Neils Bohr's discovery that spectrum lines are produced when elecrons move (1 Jan 1913 Jahr – 31 Dez 1913 Jahr)

Beschreibung:

Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. He proposed that the energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another.
