Max Planck |
father of Quantum Theory E=hv (energy absorbed/emitted directly proportional to frequency) first used Quantum (packet of energy) |
|
|
Einstein |
light is quantized, made bundles of energy called photons E = nhv (n=# of protons) |
|
|
Neils Bohr |
postulated atomic theory of atom energy of an electron is quantized line emission spectra of H atom dE = hv |
|
|
De Broglie |
suggested all matter has wave nature wave-particle duality λ = h/mv (v=velocity, m=mass, λ=wavelength) |
|
|
Heisenberg's Uncertainty Principle |
impossible to know both momentum, p, and position, x, of a particle with certainty. ∆x.m∆u ≥ h/4π concept of orbital (max probability of finding an electron of certain energy) |
|
|
Erwin Schrŏdinger |
quantum mechanical model of atom HΨ = EΨ (Ψ=wavefunction) Probability density Ψ^2 quantum #'s: n, I, m and s |
