What is...

What is the maximum number of electrons that can fit in the 5d-sublevel (or any d-sublevel)?
What is...
10 electrons
List the following in order of increasing wavelength.
microwaves, violet light, red light, ultraviolet light
What is...
ultraviolet light, violet light, red light, microwaves
What is meant by "quantized energy"?
What is...
Energy is found in specific, fixed amounts or packets.
What is the electron configuration for Barium (Ba)?
What is...
1s22s22p63s23p64s23d104p65s24d105p66s2

What is...
3 unpaired electrons
Draw the orbital notation for Sulfur...
What are the quantum numbers for the electron in the middle orbital of the 3p sub level?
What is...
3, 1, 0, + 1/2
NOT a question.
Make sure you can correctly use and interpret the three mathematical equations.
h = 6.626 • 10-34
c = 3 • 108
What is the "ground state?"
What is...
The state of the lowest possible energy for an electron.
What is the electron configuration for the ion of Selenium (Se)?
What is...
1s22s22p63s23p64s23d104p6
Using the orbital notation for Vanadium...how many unpaired electrons are there?
What is...
3 unpaired electrons
Draw the orbital notation for Magnesium...
What are the quantum numbers for the up-electron in the second s-sublevel?
What is...
2, 0, 0, +1/2
True/False: A photon of any type of electromagnetic radiation can cause an electron to jump from the first energy level to the fifth energy level.
False.
Remember that electrons will only jump from one energy level to another if it absorbs a very specific amount of energy.
What is blackbody radiation?
What is...
The emission of light from a heated object
Random question:
What is a photon?
What is...
A particle of light.
(remember light has both wave-like properties...shape of movement, frequency, wavelength....but is also composed of physical particles carrying specific amounts of energy)
Using the electron configuration for Vanadium...
How many electrons are in the 4th energy level?
What is...
2 electrons
Draw the orbital notation for Copper...
What are the quantum numbers for the down electron in the first orbital of the 3d sub-level?
What is...
3, 2, -2, -1/2
Explain why we can see color.
(make sure you can explain the absorption/emission process and ground/excited states)
What is...
Electrons in an atom are in the ground state. They absorb a specific amount of energy which causes them to move to a higher energy level (the excited state). Here the electrons are unstable so they drop to a lower energy level, emitting light/energy which we can perceive as color.
What are degenerate orbitals?
Orbitals that have the same energy
What is the orbital notation for Vanadium (V)?
What is...
*Coach Stick will come see*
Use the Aufbau principle to explain why, in any electron configuration, we begin by placing electrons in the 1s sublevel.
What is...
Electrons will always exist in the lowest possible energy level (which is the definition of the Aufbau principle).
What are degenerate orbitals?
What is...
Orbitals that have the same amount of energy (i.e. the three 3p orbitals)
Why did the ultraviolet lamp allow for the photoelectric effect to occur while the visible light lamp did not?
What is...
The photons in the visible light did not have enough energy (were below the threshold frequency) so no current was created. The photons of ultraviolet light had enough energy to cause the electrons to jump off, creating a current.
Draw an energy diagram for a Calcium atom.
THEN show an electron that absorbs light with enough energy to move it from the 4s sub level to the 5p sub level
What is...
