An example is the chromium chloride: CrCl2.
The formula of the compound and the Atomic Mass of its elements.
Chromium(III) Bromide
That would be chromium(II) sulfate, but really, chromium mostly exists as Cr(III) or Cr(VI), which would change the formula.
Chromium (II) chloride = CrCl2Chromium (III) chloride = CrCl3 Chromium (IV) chloride = CrCl4
The name of the compound with this formula is "magnesium sulfide".
Cr3Si2 is the empirical formula for a compound containing chromium and silicon an has 73.52 mass percent chromium.
This compound is the chromium phosphate.
A molecule is two or more elements bonded together, and a compound is a molecule containing at least two elements. The word formula fits in to tell you whether you have a compound or a molecule by telling you the number of elements (atoms) in the molecule.
Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
That would be chromium(IV) selenide with the formula CrSe2
Chromium(III) oxide: Cr2O3
Chromium(III) Bromide
Cr2O3
CrO can refer to chromium(II) oxide, which has the chemical formula CrO, or to chromyl chloride, which has the chemical formula CrO2Cl2. Can you please specify which compound you are referring to?
Cr2O3 is the chemical formula for chromium (III) oxide
Potassium Nitrate: Beryllium & Chromium
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
