1. A hydrogen atom in a certain excited state has its electron in a 5f subshell. The electron drops down to the 3d subshell, releasing a photon in the process.

a) For each of these subshells, give the n and l quantum numbers, and give the range of possible ml quantum numbers.

b) Determine the wavelength of light which would be emitted by this process.

c) The hydrogen atom now has a single electron in the 3d subshell. Calculate the energy (in kJ/mol) required to ionize this (excited state) hydrogen atom. (This is the energy required to remove the electron completely from the atom.)

d) The photoelectric binding energy of cesium is 183.7 kJ/mol. Light having a wavelength of 2.4m falls upon a cesium surface in an evacuated tube. Calculate the minimum deBroglie wavelength of the emitted photoelectrons.

See attached file for full problem description with proper symbols.

The best means of personal protection from radiation for emergency responders is the implementation of three basic principles: time, distance and shielding. Please show your work when answering the following questions:
a. Using the inverse square law of radiation, what Geiger counter reading would you get for a radioactive m

A radio station broadcasts at a frequency of 1MHz with a total radiated power of 5000 watts.
(a) What is the wavelength of this radiation?
(b) What is the energy (in electron-volts) of the individual quanta that compose the radiation? How many photons are emitted per second? per cycle of oscillation?
(c) A certain radio rec

Radiation: The atoms of a radioactive element are randomly disintegrating and
emitting alpha particles. The number of alpha particles emitted per second from
these atoms during a 30 second period is recorded as follows.

Describe in your own words the following terms and give at least two examples for each: a) radiation, b) radioactive,
c) ionizing radiation.
Compare and contrast deterministic and stochastic effects of ionizing radiation. What is the role of how the radiation
dose is delivered in time impact these effects?

A (N2H5)2 C3H4O4 has 1.084 x 10^24 carbon atoms. ? moles of hydrogen atoms are there in this sample
The atomic weight of hydrogen is 1.00794
There are 10 hydrogen in the given sample which is = 10.0794 atomic weight within the sample.
How do I use the amount of carbon atoms to determine how many moles of hydrogen atoms are
