Answer

Fe3+ = 1s2, 2s2, 2p6, 3s2 , 3p6 , 3d5 S2- = 1s2, 2s2, 2p6, 3s2, 3p2

Work Step by Step

The 3+ in Fe3+ means that the iron atom has lost 3 negatively charged electrons, causing it to become positive. The 2- in S2- means that it has gained 2 negatively charged electrons, causing it to become negative.
