n= 1, E=-21
A gaseous sample of this element is bombarded by photons of various energies (in these same units). Match each photon to the result of its absorption (or lack thereof) by an n=1 electron.
n=1 to n=2
n=1 to n=3
n=1 to n=4
I think the A/21 is electron ejected, but I don’t know how to figure the rest…
E = k/N2
E = -21…-9….-4….-3……0
In going from n = 1 to n = 2 we have dE = 13
Going from 1 to 3 we have dE = 17
Going from 1 to 4 we have dE = 18
Going form 1 to inf we have dE = 21
Match them up.
A is 21 so that must be the one ejected; i.e., ionized.
B is 17 so that must be 1 to 3
C and D are not absorbed.
