WebMar 24, 2016 · The electron configuration of a neutral sulfur atom will thus be "S: " 1s^2 2s^2 2p^6 3s^2 3p^4 Now, the sulfide anion, "S"^(2-), is formed when two electrons are added to a neutral sulfur atom. As you … WebPotassium has one more electron than argon and so we put that extra electron into a 4s orbital because for potassium the 4s orbital is lower energy than the 3d orbitals here. We have increasing energy and that electron goes into a 4s orbital so the complete electron configuration using noble gas notation for potassium is argon in brackets 4s 1. rumores united
