**The energies, E, for the first few states of an unknown element are shown here in arbitrary units. n 1 2 3 4 … E -42 -18 -8 -6 0A 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 Result OPTIONSA 42 n=1 to n=2B 34 n=1 to n=3C 31 n=1 to n=4D 24 electron ejected**

## THIS IS THE BEST ANSWER ๐

1) n = 1 -> n = 2: delta E = -5 + 11 = 6. The answer is D

2) n = 1 -> n = 3: delta E = -2 + 11 = 9. The answer is B

3) n = 1 -> n = 4: delta E = -1 + 11 = 10. No solution available

4) n = 1 -> delta Infinity E = 11. The answer is A.

5) C would not be accepted, as there is no shift to delta E of 8.
