16 QuestionsShow answers
  • Question 1
    30 seconds
    Q. Define "quantized"
    answer choices
    The electron's mass is very small. 
    The electron is actually a wave.
    The position & momentum of the electron cannot be known at the same time. 
    The electron is limited to certain positions in the atom.
  • Question 2
    30 seconds
    Q. "Energy is quantized." 
    answer choices
    Planck
    Heisenberg
    de Broglie
    Schrodinger
  • Question 3
    30 seconds
    Q. "wave theory"
    answer choices
    Planck
    Heisenberg
    de Broglie
    Schrodinger
  • Question 4
    30 seconds
    Q. "Electrons have particle and wave-like properties."
    answer choices
    Planck
    Heisenberg
    de Broglie
    Schrodinger
  • Question 5
    30 seconds
    Q. created an equation to treat the electron as a wave
    answer choices
    Planck
    Heisenberg
    de Broglie
    Schrodinger
  • Question 6
    30 seconds
    Q. Why are we not allowed to know the position and momentum of the electron? 
    answer choices
    the size of the nucleus
    the electron's mass is too small
    the electron behaves like a wave
    it moves too fast
  • Question 7
    30 seconds
    Q. The position & momentum of the electron cannot be known at the same time. 
    answer choices
    Planck
    Heisenberg
    de Broglie
    Schrodinger
  • Question 8
    30 seconds
    Q. Why do we not use Bohr's planetary model today?
    answer choices
    it is too specific; we are not allowed to know the electron's specific location
    it represented the nucleus far too largely
    it is too vague; we have more specific information to use now
    it placed the electrons too close to the nucleus
  • Question 9
    30 seconds
    Q. No two elements have the same line spectrum. 
    answer choices
    True
    False
  • Question 10
    30 seconds
    Q. How is the Quantum Mechanical Model different from Bohr's planetary model?
    answer choices
    The QMM shows the probability of the electron's location.
    The planetary model shows the probability of the electron's location.
    The QMM shows the exact location of the electron. 
    The QMM does not include a nucleus.
  • Question 11
    30 seconds
    Q. represents the distance the electrons are from the nucleus
    answer choices
    energy level 
    sublevel
  • Question 12
    30 seconds
    Q. represents an area of probability of the electron's location, called s, p, d, or f
    answer choices
