Ey = _______eV.
c) The kinetic energy of the ejected electron is K =
_________eV

a
hydrogen atom initially in its n=4 state absorbs a photon of
wavlength 238.5 nm, which is enough to ionize it. how much kinetic
energy in eV does the ejected electron have?

A ground-state H atom absorbs a photon of wavelength
92.62 nm. What higher energy level did the electron
reach?

4 a) A hydrogen atom in the ground state absorbs a photon of
wavelength 97.2 nm. What energy level does the electron reach?
b) This excited atom then emits a photon of wavelength 1875.4
nm. What energy level does the electron fall to?

An atom absorbs a photon with wavelength 500 nm and subsequently
emits a photon with wavelength 660 nm.
a) Determine the energy absorbed by the atom.
b) Assume that the atom is a solid particle with mass 3.3×10−26
kg and is initially at rest. Determine the speed of the atom after
it has emitted the photon, assuming that any additional energy it
acquired only contributed to its motion.

What energy level does the electron fall to?
-I know this question has already been asked on Chegg but each
question I go to has different calculations and I can't get the
right answer.

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...
