Homework Statement
1. If Bohr’s theory and wave-mechanics predicts the same results for energies of hydrogen atom states, then why do we need wave mechanics with its greater complexity?
2. Compare Bohr’s theory and wave mechanics. In what respect do they differ?
3. Why don’t we observe space quantization for spinning top?
4. Why does it take more energy to remove an electron from neon (z = 10), than from sodium (z = 11)?
5. What is the de Broglie wavelength for an electron (me = 9.11 10-11 kg) moving with a speed of 1.00 107 m/s?

Could just do the last one...
5.
λ = h / mv
= 6.634 * 10-34 / (9.1* 10-11* 1* 107)
= 0.72 * 10 -30 m
