Potassium forms an ionic compound with sulfur. Describe what happens when two atoms of potassium react with one atom of sulfur. Give your answer in terms of electron transfer.
Electrons are transferred from potassium to sulfur. 2 potassium atoms each lose one electron forming K+ / 1+ ionsSulfur atoms gain 2 electrons forming S2- / 2- ions. This results in the ionic formula K2S
