TiSe.
The formula for potassium selenide is K2Se. It consists of two potassium atoms and one selenium atom.
The chemical formula for zinc selenide is ZnSe.
The ionic compound formed between beryllium and selenium is beryllium selenide. Beryllium (Be) has a +2 charge, while selenium (Se) typically has a -2 charge. To balance the charges, one beryllium ion combines with one selenide ion, resulting in the formula BeSe.
Sulfur and phosphorus would most like form the compound P2S5
The chemical formula for sodium selenide is Na2Se.
titanium (II) selenide = SeTi
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 formula for cobalt(II) selenide is CoSe. It is composed of one cobalt ion (Co^2+) and one selenide ion (Se^2-).
A selenide contain the anion Se(2-).
V2Se5 is the formula for vanadium V selenide.
The chemical formula for copper selenide is Cu2Se.
The empirical formula of phosphorus selenide is P2Se3.
The chemical formula for boron selenide is B2Se3.
Ca+2 Se-2 -----> these are the ions and their chargesCalcium selenide (CaSe)-------> the charges must equal zero; since they already do, there is one ion of each in the compound.
Formula: CdSe
Formula: Se2-
Formula: K2Se
