Inverse
Listed below are motion in atoms and molecules. All of them can be amplified by photons of light at different energies. What EMR causes exciting a valence electron? Give a real life example as well.
Ultraviolet (sunburns)
What will happen if you have a photon that has 3.0 eV hit a metal surface with a work function of 2.3eVs?
What does "l" quantum number mean? (Name and definition)
Known as Angular Momentum and defines the subshell and forms the four blocks (shapes of orbitals) on the periodic table s, p, d, f.
Which wave has higher energy quantum energy between blue light and ultraviolet light?
Ultraviolet
Why do nanometers or micrometers have to be converted during calculations?
The speed of light is in mks units (meters per second or m/s)
Listed below are motion in atoms and molecules. All of them can be amplified by photons of light at different energies. What EMR causes rotating a gas molecule? Give a real life example as well.
Microwaves (cooking food)
What is the relationship between mass and wavelength in the DeBroglie equation?
Inversely Related

Potassium is one of the most well-known elements in the alkali metal _______. It is in the _________ which makes it a ________ element. Its single valence electron is in the ________ subshell of the _______ shell, making it very reactive. It reacts readily with non-metals to form _________.
family; s block; main group; l=0; n=4, salts
What is the relationship between quantum energy of light wave and wavelength?
Inverse
What is the equation that relates Energy and wavelegnth?
E=hc/lambda
Listed below are motion in atoms and molecules. All of them can be amplified by photons of light at different energies. What EMR causes exciting inner shell electrons? Give a real life example as well.
X-Rays (medicinal)
Explain what wave particle duality of LIGHT and MATTER mean.
MATTER has a wave and particle nature and LIGHT has a wave and particle nature.
Explain Pauli Exclusion Principle.
No two electrons can have the same four quantum numbers which means that you can only put two electrons of opposite spin in the same orbit.
Which type of light will affect -OH groups by causing vibrations such as the alcohol breath test?
Infrared Light
What is the frequency of a 1 nm photon?
3x1017 Hz
Listed below are motion in atoms and molecules. All of them can be amplified by photons of light at different energies. What EMR causes vibrating a molecular bond? Give a real life example as well.
Infrared (night vision)
What was the wavelength of Dr. Laude when he weighed 100 kg and being quite the athlete could run 10 m/s effortlessly (okay, so I'm rounding up)? How does this answer compare to an electron and what does the results suggest from a practical perspective?
6x10-37 m
Who developed quantum mechanics?
Schrodinger and it helps explain the wave behavior of electrons. We cannot know the exact location of an electron, but we can know its most probable location. Not all locations are possible. There are rules for where electrons are found known as quantum rules.
Making a light "brighter" having more intensity (such as a dim blue light versus a bright blue light) will likely affect which of the following parts of the wave? (amplitude, frequency, wavelength)
amplitude
What is the frequency of a 1 micron photon?
3x1014 Hz
Listed below are motion in atoms and molecules. All of them can be amplified by photons of light at different energies. What EMR causes Spinning nuclei? Give a real life example as well.
Radio Waves (MRI)
Which equation can be used to calculate the speed of the ejected electrons?
KE = 1/2mv2
Use the Rydberg equation to calculate the frequency of a hydrogen electron that is being ionized. (An ionized electron absorbed enough energy to remove an electron from a substance)
3.3 x 1015 Hz
