1. Which of the following is the best paraphrasing of the Heisenberg uncertainty principle?
(a) Only if you know the exact position of a particle can you know the exact momentum of the particle.
(b) The larger the momentum of a particle, the smaller the position of the particle.
(c) The more precisely you know the position of a particle, the less well you can know the momentum of the particle.
(d) The better you know the position of a particle, the better you can know the momentum of the particle.
(e) How well you can determine the position and momentum of a particle depends on the particle's quantum numbers.
2. Which of the following is required by the Pauli Exclusion Principle?
(a) No electron in an atom can have the same set of quantum numbers as any other electron in that atom.
(b) Each electron in an atom must have the same n value.
(c) Each electron in an atom must have different values.
(d) Only two electrons can be in any particular shell of an atom.
(e) No two electrons in a collection of atoms can have the exact same set of quantum numbers.
3. Under what condition(s) can the exact location and velocity of an electron be measured at the same time?
(a) The electron is in the ground state of the atom.
(b) The electron is in an excited state of the atom.
(c) The electron is free (not bound to an atom).
(d) Both (a) and (b).
(e) Never.
