Cr2S3 is Chromium sulfide.
Cr2S3 is a chromium 3
The formula for chromium(III) sulfide is Cr2S3.
The chemical formula Cr2S3 is for dichromium trisulfide.
Cr2S3 is Chromium Sulfide.
It is Chromium III (3)
The chemical formula of chromium (III) trisulfide is Cr2S3.
Cr2S3 can be broken down. You know that when combined, the charges will flip and go to subscript. That means that it broken down, it is Cr^3 x S^2. Cr^3 is the transition metal, Chromium III. The S stand for Sulfur. So the answer is Chromium (III) Sulfide
The correct name is Chromium (III) Sulfide Since Chromium is a transition metal and we know that it is in the ionic form of Cr 3+. Make sure and identify that,... We DO NOT name it according to covalent rules... it is not called Dichromium Trisulfide... that would be incorrect since this is a ionic bond.
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.
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.
