Energies in Photons of Elements

The energies, E, for the first few states of an unknown element are shown here in arbitrary units.
n 1 2 3 4 ... ?
E -11 -5 -2 -1 ... 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.
