2) Find the energy required to ionize a ground state hydrogen atom.
That is, what is the energy required to make the transition from n
= 1 to n =∞. Hint: Notice the placement of the infinity in the
denominator of a fraction. To be able to arrive at the answer for
this question, you will need to approximate the fraction with the
infinity symbol.
Put your final for
ENERGY here with
units!
3) If an electron in a hydrogen atom relaxes to the second energy
level, emitting a photon of wavelength 410.2 nm, what higher
energy level did it start at?
Put your final answer
for n here!
4) Consider an electron transition in a hydrogen atom from n = 5 to
n = 2, versus a transition from n = 3 to n = 2. Do not perform a
calculation to answer the following questions.
a. Which transition emits a higher energy photon? How can
you tell?
Put your typed answer here, by clicking on these words
and typing! Resize the space as needed, if you need
more room.
b. One of these transitions for corresponds to a red photon, and
the other to a blue photon. Which transition emits the red
photon?
Put your typed answer here, by clicking on these words
and typing! Resize the space as needed, if you need
more room.
5) Consider an electron transition in a hydrogen atom from n = 3 to
n = 2, versus a transition from n = 2 to n = 1. Do not perform a
calculation to answer the following questions.
a. Which transition emits a higher energy photon? How can
you tell?
Put your typed answer here, by clicking on these words
and typing! Resize the space as needed, if you need
more room.
b. One of these transitions corresponds to a photon in the
visible part of the spectrum, while the other is not visible to
the human eye due to the higher energy.
i. Which transition emits the photon out of the visible
range?
Put your typed answer here, by clicking on these words
and typing! Resize the space as needed, if you need
more room.
ii. Is it more likely in the UV-range, or the IR-range?
Put your typed answer here, by clicking on these words
and typing! Resize the space as needed, if you need
