Se-2 NH4+1 <--- these are the ions and their charges Se-2 NH4+1 NH4+1 <--- the charges have to add up to zero, so one -2 selenium ion cancels out two +1 ammonium ions Se(NH4)2 <--- simplify
The empirical formula of phosphorus selenide is P2Se3.
Almost certainly you are looking for Titanium(IV) Selenide, TiSe2, though the Titanium(III) compound, Ti2Se3 may exist as well. You should be more specific :)
The correct name for the compound NH4S2 is ammonium sulfide.
The balanced equation for the reaction between cesium (Cs) and selenium (Se) to form cesium selenide (Cs2Se) is: 2Cs(s) + Se(s) -> Cs2Se(s)
