Questions
  1. Statement is true
    Yes
    Statement
    Bohr explained the spectrum of the hydrogen atom.
  2. Statement is true
    No
    Statement
    Bohr's model works equally well for multi-electron atoms.
  3. Statement is true
    Yes
    Statement
    Bohr allowed only certain orbits, each with a specific energy.
  4. Statement is true
    No
    Statement
    Bohr's model accounts for the wave nature of the electron.
  5. Statement is true
    Yes
    Statement
    Bohr's model contradicts the Heisenberg uncertainty principle.
It fixed hydrogen and broke on everything else. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.

Missing parts
  1. Answer
    position
    Choices
    1. position
    2. mass
    3. charge
  2. Answer
    velocity
    Choices
    1. velocity
    2. energy
    3. spin
  3. Answer
    Heisenberg uncertainty
    Choices
    1. Heisenberg uncertainty
    2. Pauli exclusion
    3. Aufbau
Complete the statement
A clearly defined orbit requires knowing the electron's exact {0} and exact {1} at the same time. The {2} principle says that is impossible.
A well-defined orbit needs both position and velocity known at once, which the uncertainty principle forbids. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.
