Chromium VI sulphate Cr(SO4)3
Cr2S3
CrS3 is the formula of chromium(VI) sulfide
Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
Chromium (ii) sulfide is CrS. The ii indicates that chromium can take on different valence characteristics, here sharing two electrons with the sulphur atom. The same elements can also make a different mineral compound, Cr2S3 where Chromium atoms share 3 electrons instead of two.
The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Formula for potassium sulfide is K2S.
CrS3 is the formula of chromium(VI) sulfide
Chromium III is Cr3+. The roman numeral tells you the charge. Sulfide is S2-. You can figure this out from the periodic table. Sulfur needs two electrons to be like Argon, the next noble gas. When they form a compound, they combine in a ratio such that the total positive charge balances the total negative charge. 2 Cr3+ ions have a total charge of +6. 3 S2- ions have a total charge of -6. So the formula is Cr2S3.
Strontium Sulfide
BeS is the chemical formula of beryllium sulfide.
Chromium (ii) sulfide
Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
