Question

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?

Answer #1

A hydrogen atom in the ground state absorbs a photon of
wavelength 95.0 nm.
What energy level does the electron reach?
This excited atom then emits a photon of wavelength 434.1 nm.
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.

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

A ground state hydrogen atom absorbs a photon of light having a
wavelength of 92.57 nm. It then gives off a photon having a
wavelength of 954.3 nm. What is the final state of the hydrogen
atom? Values for physical constants can be found here.

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 mercury atom is initially in its lowest possible (or ground
state) energy level. The atom absorbs a photon with a wavelength of
185 nm and then emits a photon with a frequency of 4.924 x 10^14
Hz. At the end of this series of transitions, the atom will still
be in an energy level above the ground state. Draw an energy-level
diagram for this process and find the energy of this resulting
excited state, assuming that we assign a...

The electron in a hydrogen atom falls from an excited energy
level to the ground state in two steps, causing the emission of
photons with wavelengths of 656.5 nm and 121.6 nm (So the in the
first step the 656.5 nm photon is emitted and in the second step
the 121.6 nm photon is emitted). What is the principal quantum
number (ni) of the initial excited energy level from which the
electron falls?

1. A hydrogen atom, initially in the first excited state
(initial ni = 2), absorbs a photon of wavelength 656.30 nm.
(a) (5) What is the final state ? In other words, solve for the
FINAL nf . Show all work.
(b) (5) What would be the wavelength of a photon, which , when
absorbed by the atom, ionizes an electron from the first excited
level ?
2. X-rays with initial wavelength λ = 0.0665 nm undergo Compton
scattering.
(a)...

a) After this atom absorbs a 77-nm photon, the electron is
ejected. The energy of the absorbed photon is....
b) The kinetic energy of the ejected electron is...

A hydrogen atom is in its third excited state. The atom emits a
1.88E+3nm wavelength photon. Determine the maximum possible orbital
angular momentum of the electron after emission. Express your
answer as multiples of hbar.

A Li atom absorbs with a wavelength 619.6nm, and is excited from
the 2s ground state to the 2p excited state. If the first
ionization of Li is 520.2kJ/mol, the wavelength of the photon
required to ionize the excited Li atom is closest to
A) 365.7nm
B) 619.6nm
C) 273.5nm
D) 229.9nm
E) 38.18nm
