Assertion and reason: filling orbitals

Read exercise and reference answers
Questions
  1. Reason
    Pauli forbids two electrons in an atom sharing all four quantum numbers.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    An orbital holds at most two electrons.
  2. Reason
    Hund's rule of maximum multiplicity requires single occupancy first.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Electrons spread out before pairing up in a subshell.
  3. Reason
    Rutherford discovered the nucleus by alpha-particle scattering.
    Verdict
    Both are true; the reason does not explain the assertion.
    Assertion
    Orbitals fill in order of increasing energy.
The last round pairs two true halves that do not explain one another. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.
