1. If one prepared a gas-phase Be3+ ion with its electron in a 4f orbital, it would take the same amount of energy to remove that electron as it does to ionize a ground state H atom. Justify or Refute.

2. If 300 nm light with a certain intensity on a metal surface causes the metal to emit a stream of electrons, then 45- nm light of the same intensity will cause the metal to emit the same number of electrons per unit time, but the emitted electrons will be traveling at a lower speed. Justify or Refute.

3. If a neutral gas-phase atom has a partially filled p subshell in its ground state, all its other subshells are either completely filled or completely empty. Justify or Refute.
