• Question 1
30 seconds
Q. Define "quantized"
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."
Planck
Heisenberg
de Broglie
Schrodinger
• Question 3
30 seconds
Q. "wave theory"
Planck
Heisenberg
de Broglie
Schrodinger
• Question 4
30 seconds
Q. "Electrons have particle and wave-like properties."
Planck
Heisenberg
de Broglie
Schrodinger
• Question 5
30 seconds
Q. created an equation to treat the electron as a wave
Planck
Heisenberg
de Broglie
Schrodinger
• Question 6
30 seconds
Q. Why are we not allowed to know the position and momentum of the electron?
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.
Planck
Heisenberg
de Broglie
Schrodinger
• Question 8
30 seconds
Q. Why do we not use Bohr's planetary model today?
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.
True
False
• Question 10
30 seconds
Q. How is the Quantum Mechanical Model different from Bohr's planetary model?
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
energy level
sublevel
• Question 12
30 seconds
Q. represents an area of probability of the electron's location, called s, p, d, or f
energy level
sublevel
• Question 13
30 seconds
Q. "Electrons in the same orbital have opposite spin."
aufbau principle
Hund's Rule
Pauli Exclusion Principle
Uncertainty Principle
• Question 14
30 seconds
Q. "Electrons fill lower energy orbitals before filling higher energy orbitals."
aufbau principle
Hund's Rule
Pauli Exclusion Principle
Uncertainty Principle
• Question 15
30 seconds
Q. "Electrons fill equal energy orbitals singly before pairing."
aufbau principle
Hund's Rule
Pauli Exclusion Principle
Uncertainty Principle
• Question 16
30 seconds
Q. "There are two electrons maximum in an orbital."
