Question #1 : Write the abbreviated electron configuration for the element galli

Question

Question #1 : Write the abbreviated electron configuration for the element gallium, Ga, and determine the four quantum numbers for its unpaired electron.

Abbreviated e- configuration of Ga: ________________

For the unpaired electron: n =____, l = ____, ml = ____, ms = ____

Question #2 : A particular electronic transition in a hydrogen atom results in a photon of light with a wavelength of 97 nm being emitted. Calculate the energy difference between the two energy levels involved in the transition.

Question #3 : What is the frequency of light (in Hertz) that has a wavelength of 585 nm?

Explanation / Answer

according to chegg guide lines i can answer only one part of the question

Questiom-1

atomic number of Ga is 31

general electronic configuration is

1s2 2s2 2p6 3s2 3p6  3d10 4s2 4p1

but here

Ar =1s2 2s2 2p6 3s2 3p6

so abbreviated electronic configuration is

[Ar] 3d10 4s2 4p1
