That would be the bichromate or sometimes called the dichromate ion. Example: Sodium bichromate (or sodium dichromate) is Na2Cr2O7.
The usual name is "dichromate", but I think the systematic name is closer to "heptoxidodichromate(VI)".
Dichromate is Cr2O72.
Lithium dichromate
I believe it is called dichromate.
Dichromium trioxide
dichromate
For ionic compounds such as the one mentioned above, naming them is relatively easy. As we all know, an ionic compound consists of a metal ion(which is usually positive) and a negative ion. Hence, the names for metallic compounds are always in the following format: Name of metal + Name of negative ion However, do take note that for transition metals, the oxidation state has to be included. This is because transition metals have multiple oxidation states. The oxidation state of the metal is presented by: Metal (oxidation number). For example, rust is Iron (III) oxide. Cr2O3 is hence named chromium (III) oxide.
Aluminum Phosphide
Chromium (II) chloride = CrCl2Chromium (III) chloride = CrCl3 Chromium (IV) chloride = CrCl4
cadmium oxide
Barium oxide
Cr2O3 is ionic.
It is ionic because chromium is a metal.
It is ionic compound as the difference in the electronegativity between chromium and oxygen is more than 1.7
Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal.
Cr2O3 is an oxide.
Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
Cr2O3 is known as Chromium(III) oxide. Please see the "related links" below for more information about this compound.
The compound Cr2O3 is chromium(III) oxide. It is a naturally inorganic occurring compound and it is used primarily as green pigment.
The name for the ionic compound FeO is iron(II) oxide.
Cr2O3 is the chemical formula for chromium (III) oxide
I think KCI ionic compound name is Potassium Chloride.
