Answer #1

4. [15] Light is emitted from a hydrogen atom as an electron in
the atom jump from the n=9 orbit
to the n=3 orbit.
(a) [7] What is the energy of the emitted photon in eV?
(b) [4] What are the frequency and wavelength of the photon?
(c) [4] In which frequency range (UV, visible, IR) is the
emitted electromagnetic radiation?
Justify your answer.

A photon is emitted from a hydrogen atom when an electron goes
from the n = 6 to the n = 2 state. What kind of electromagnetic
radiation is this? Select one:
a. Visible Light
b. Ultraviolet Light
c. Infrared Radiation
d. X-Ray Radiation
e. Microwave Radiation

In the Bohr model of the atom, what is true about the light
emitted by an atom?
1. The emitted photonâ€™s frequency is the classic frequency at
which an electron vibrates.
2. An electron accelerating around its orbit continuously emits
radiation.
3. None of these
4. The energy of the emitted photon is equal to the difference
in energy between the two orbits.

a. what is the energy of the emitted photon if an electron in
the hydrogen atom makes a transition from the n=7 state to the n=2
state?
b. Now, Imagine there is a photon with the same wavelength. What
is the speed of this photon?

Calculate the energy of the emitted photon as well as the
wavelength and frequency of electromagnetic radiation emitted from
the hydrogen atom when the electron undergoes the transition from n
= 5 to n = 1. In what region of the spectrum does this line
occur?

What is the wavelength of the photon emitted as the electron in
the hydrogen atom transitions from the 3rd to 2nd level? What is
the frequency of the photon and what is the energy carried by the
photon?
got -6606 A for the first one and I'm not sure if I'm doing it
right

(1)
Part A: If a electron in a hydrogen atom makes a transition from
ground state to n = 8 level what wavelength of light in (nm) would
be needed for the abosorbed photon to cause the transition?
Part B: If the same electron falls to a lower level by emmitting
a photon of light in the Paschen series what is the frequncy of
light in (Hz) thats emitted?
(2) When a photon have a wavelength of 195nm strikes the...

What is the wavelength of light (in m) emitted by a hydrogen
atom when an electron relaxes from the 5 energy level to the 3
energy level?

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...

Q1)

Q2)
What would be the wavelength of radiation emitted from a
hydrogen atom when an electron moves from the n =
2 to n = 1energy level?
In what region of the spectrum does this radiation lie?
Wavelength = ________nm
Region = _________(ultraviolet or visible or infrared)
