Assertion and reason: models

Read exercise and reference answers
Questions
  1. Reason
    Classical physics predicts any orbiting electron must radiate.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Bohr had to postulate stationary orbits rather than derive them.
  2. Reason
    Each element emits its own characteristic set of lines.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Line spectra are useful evidence about atomic structure.
  3. Reason
    An atom as a whole is electrically neutral.
    Verdict
    The assertion is false and the reason is true.
    Assertion
    Thomson's model explains scattering results.
The reason must genuinely explain the assertion. Source: syllabus Physics, Ch 12 Atoms.
