Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
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.
The stable isotope of chromium is chromium-52. Other isotopes of chromium include chromium-50, chromium-53, chromium-54, and chromium-55, but not chromium-151.
Chromium is a 3d element. chromium is a metal.
Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
Chromium ore is a source of the metal Chromium.
This compound is chromium hydroxide.
There are three stable isotopes of Chromium 52Cr, 53Cr, and 54Cr.
Na2Cr2O7 is an ionic compound. It is composed of sodium ions (Na+) and dichromate ions (Cr2O7 2-), which are held together by ionic bonds due to the large difference in electronegativity between sodium and chromium.
Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
Chromium has several valence states, only one of which is Chromium III. States 2, 3, and 6 are most common but 1, 4, and 5 are possible. Total chromium means the amount of chromium in all valence states.
