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
