An energy of 80.02eV is needed to ionize an electron from the ground state of a hydrogen- like atom. What is the maximum wavelength of a photon that accomplishes this task (in nm )?

In a ground state atom of As how many electrons total will have the quantum number l=2?

An electron in the n = 6 level drops to the n = 1 level in a hydrogen atom. Calculate the frequency of the emitted photon. Report your answer in s-1. Some potentially useful information is provided below. Please write out your work, show equation(s) that you used, etc. This will make it possible to give partial credit. (This does not have to be long. For example, if I were given the radius of a circle and asked to calculate area, the work that I would should would simply show A = pi x r^2 and then the calculation.) En = −2.18 × 10−18 J (1n2)En = -2.18 × 10-18 J (1n2) h = 6.626 ×10−34 J s h = 6.626 ×10-34 J s  c = 3.00 ×108 m/s
