I believe it is 18. I'm not 100% sure, but at least you have some kind of an answer. Sorry if this is inconvenient to you in any way.

How many electrons can an atom's fourth outer energy level contain?

The fourth outer energy level of an atom can contain a maximum of 32 electrons. This is because each energy level can hold a maximum of 2n^2 electrons, where n is the principal quantum number of the energy level. In this case, the fourth energy level has a principal quantum number of 4, so it can hold 2(4^2) = 32 electrons.
