Quantum Mechanics History

The contribution of Planck is...

• Light is both a wave and a particle (explanation of the photoelectric effect)

• Matter is both a particle and a wave

• Credited with inventing the periodic table

• Energy comes in packets called quanta

The contribution of Einstein is...

• Light is both a wave and a particle (explanation of the photoelectric effect)

• Uncertainty Principle: You can’t know both

  the location and velocity of a particle exactly.

The contribution of Bohr is...

• Wave functions, orbitals, quantum mechanical model of the atom

• His model of the atom, electrons move in fixed orbits around the nucleus like planets around the sun, energy levels are quantized.

• Credited with inventing the periodic table

The contribution of DeBroglie is...

• Matter is both a particle and a wave

• Light is both a wave and a particle (explanation of the photoelectric effect)

• Wave functions, orbitals, quantum mechanical model of the atom
