Louis de Broglie
Matter is composed of particles that are quantized and have dual nature
Related electron spin to the arrangement of electrons in the atom
Electrons occupy equal energy orbitals so that a maximum number of unpaired electrons result
The position and momentum of a moving particle cannot be exactly determined simultaneously
