Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. [3] [4]
Chromium is a chemical element; it has symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, ...

Chromium(II) acetate hydrate, also known as chromous acetate, is the coordination compound with the formula Cr 2 (CH 3 CO 2) 4 (H 2 O) 2. This formula is commonly abbreviated Cr 2 (OAc) 4 (H 2 O) 2 . This red-coloured compound features a quadruple bond .
The darker blue spheres represent chromium atoms outside of the polyhedra. Cr 23 C 6 is the prototypical compound of a common crystal structure, discovered in 1933 [1] as part of the chromium-carbon binary phase diagram. Over 85 known compounds adopt this structure type, [2] which can be described as a NaCl-like packing of chromium cubes and ...
The flame test carried out on a copper halide.The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample.
Chromium(III) chloride (also called chromic chloride) is an inorganic chemical compound with the chemical formula Cr Cl 3. It forms several hydrates with the formula CrCl 3 · n H 2 O , among which are hydrates where n can be 5 (chromium(III) chloride pentahydrate CrCl 3 ·5H 2 O ) or 6 (chromium(III) chloride hexahydrate CrCl 3 ·6H 2 O ).
