Decide how the electrons in the following table would be listed, if they were listed in order of increasing electrostatic potential energy. That is, select "1" next to the electron with the lowest electrostatic potential energy, select "2" next to the electron with the second lowest electrostatic potential energy, and so on.

electron	location	electrostatic potential energy
A	3.1 nm from a cation with a charge of +2	(choose one)1 (lowest)234 (highest)
B	1.7 nm from a cation with a charge of +2	(choose one)1 (lowest)234 (highest)
C	4.4 nm from a cation with a charge of +2	(choose one)1 (lowest)234 (highest)
D	1.7 nm from a cation with a charge of +3
