So, the correct name is chromium(VI) carbonate.
Chromium Carbonate, Cr2(CO3)3 Powder (CAS No.
Chromium(III) cation. Chromic cation. 16065-83-1. chromium(3+) ion. Cr3+
What is Chromic oxide? Cr2O3 is an inorganic compound with chemical name Chromic oxide. It is also called Dichromium trioxide, or Chromium (3+) oxide, or Chromium (III) oxide. It naturally occurs in a mineral eskolaite, which is mostly found in chromium-rich skarns, tremolite, chlorite veins, and meta quartzites.
chromium oxide, also known as chromium sesquioxide or chromic oxide, Cr2O3, in which chromium is in the +3 oxidation state. It is prepared by calcining sodium dichromate in the presence of carbon or sulfur.
Carbonate Ion is a polyatomic ion with formula of CO3(2-). NCI Thesaurus (NCIt) Carbonate is a carbon oxoanion. It is a conjugate base of a hydrogencarbonate.

Chromium Carbonate Chemical Formula
Chromium(III) Carbonate is a chemical compound which can be represented using the chemical symbol Cr2(CO3)3.
Potassium chromate is a potassium salt consisting of potassium and chromate ions in a 2:1 ratio. It has a role as a carcinogenic agent and an oxidising agent. It contains a chromate(2-).
It has a total of 24 electrons.
Most common oxidation state: +3; +2 and +6 also exist. The +3 oxidation state is the most stable. Characteristics: Chromium is a silvery, rather brittle metal.
Preparation. Dehydration with trimethylsilyl chloride in THF gives the solvate: CrCl3 · 6 H2O + 12 Me3SiCl → CrCl3(THF)3 + 6 (Me3Si)2O + 12 HCl.
Two Cr3+ ions have a total charge of 6+ and three O2- ions have a total charge of 6- , giving the combination a net charge of zero. The simplest ration of Cr3+ to O2- is 2:3 , and the formula is Cr2O3 . Note the charge without its sign on one ion becomes the subscript of the other ion.
Chemical Nature of Cr2O3
Chromium has three different oxides. CrO has an oxidation number +2, and is a basic oxide, while CrO3 is acidic with a +6 oxidation number. Cr2O3 is amphoteric. Even if it is insoluble in water, it dissolves in acid to give hydrated chromium ions [Cr(H2O)6]3+.
