Question

Consider the following four transitions in a hydrogen atom.

(i) ni = 6, nf = 9 (ii) ni = 6, nf = 12 (iii) ni = 10, nf = 12 (iv) ni = 9, nf = 6

(a) Give the wavelength of the longest-wavelength photon that can be emitted or absorbed by these transitions. m

(b) Give the wavelength of the shortest-wavelength photon that can be emitted or absorbed by these transitions. m

(c) For which of these transitions does the atom lose energy? (Select all that apply.)

(i) since electron emits a photon (i) since electron absorbs a photon (ii) since electron emits a photon (ii) since electron absorbs a photon (iii) since electron emits a photon (iii) since electron absorbs a photon (iv) since electron emits a photon (iv) since electron absorbs a photon Incorrect: Your answer is incorrect.

Answer #1

Q6] A hydrogen atom transitions from the ni = 5 state down to
the ground state. In the process it emits a photo of light. The
photon then strikes a photo-electric material with a work function
of Wo = 7.5eV . a) What is the wavelength of the photon emitted
from the transition of the hydrogen atom? b) What is the kinetic
energy of the electron ejected from the photo-electric
material?

A hydrogen atom (Z=1) is in the third excited state. It makes a
transition to a different state, and a photon is either emitted or

Answer the following questions using the Bohr model of the
hydrogen atom.
a) A hydrogen atom is the n = 3 excited state when its electron
absorbs a photon of energy 4.40 eV. Draw a diagram roughly to
scale, of relevant energy levels for this situation. Make sure to
show and label the initial energy of the H atom in the n=3 state,
the energy level at which this atom loses its electron, and kinetic
energy of the electron.
b)What...

1. a. A photon is absorbed by a hydrogen atom causing an
electron to become excited (nf = 6) from the ground state electron
configuration. What is the energy change of the electron associated
with this transition?
b. After some time in the excited state, the electron falls from
the n = 6 state back to its ground state. What is the change in
energy of the electron associated with this transition?
c. When the electron returns from its excited...

Which of the following electron transitions in a hydrogen atom
results in the emission of photons with the shortest wavelength? A)
n = 3 to n = 4 B) n = 1 to n = 3 C) n = 6 to n = 4 D) n = 7 to n =

I have solved some of the questions and the answers are the
following
1. 1.62 * 10^-4 eV
2. 0.00765432 m
4. 5.909 * 10^-3 m
5. 3.33 * 10^-10 m
So the only questions missing are question #3 and question #6.
If when solving questions 1, 2, 4 and 5, you do not get the same
values as posted here, please do not even bother to submit question
3 and question 6 because you most likely have it wrong...
