When potassium and sulfur react to form potassium sulfide an ionic compound what happens?

Answer 1

The potassium atom gives up one electron, and the sulfur atom acquires two electrons (hence, it takes two potassium and one sulfur to form potassium sulfide, K2S).

Answer 2

In the reaction between potassium and sulfur to form potassium sulfide, potassium transfers one electron to sulfur to achieve a stable electron configuration. This results in the formation of an ionic compound where potassium becomes a cation with a positive charge and sulfur becomes an anion with a negative charge. The strong electrostatic attraction between the oppositely charged ions leads to the formation of a crystalline lattice structure in potassium sulfide.
