On the surface, this would be magnesium sulphide, but magnesium sulphide is MgS. The compound here, Mg2S2, has the same ratio of magnesium to sulfur as MgS, but this compound, Mg2S2 is not one that exists. A molecule made of two atoms of magnesium and two atoms of sulfur, Mg2S2, will not form. A link can be found below to the "real" magnesium sulphide.
K2Se is potassium selenide or more precisely dipotassium selenide. As for KSe that probably doesn't exist, if it did it would be monopotassium selenide
The systematic name of this ionic compound is Tin(IV) Selenide.
A selenide contain the anion Se(2-).
Tin(IV) selenide
