What does Cs2S stand for in the periodic table?
Cs2S is Caesium sulphide. Separately 'Cs' (Caesium) is found in Group 1. and 'S' (sulphur) is found in Group 6. As a molecule Cs2S is NOT in the periopdic table, only elements are found in ther periodic table. Cs2S means that there are two(2) caesium atoms combined to one(1) sulphur atom.
