The energies, E, for the first few states of an unknown element are shown here in arbitrary units.

n 1 E -11

n 2 E -5

n 3 E -2

n 4 E -1

n ... E ...

n infinite E 0

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.

Photon/Energy

A/11

B/9

C/8

D/6

Choices:

n=1 to n=2

n=1 to n=3

n=1 to n=4

electron ejected

not absorbed

In order to get 11, I need to go from 11 to zero. Zero is infinity which means the electron was ejected (ionized).

To get 9 I need 2 to 11 and that is n = 1 to n = 3. Can you take it from here?

I need help with the rest.

What is C/8? not absorbed?

Is D/8 n=1 to n=2?
