Chromium - WikipediaChromium Piccolinate is a salt of the trace metallic element chromium (Cr), essential in glucose metabolism Found in vitamins and mineral supplements, Chromium may be necessary for utilization of dietary sugars and carbohydrates by optimizing the effects of insulin Animal studies suggest that chromium picolinate may be carcinogenic, it enters cells directly and can causes mutations...

Why do the electron configurations of chromium and copper ,Jul 07, 2014· Some elements do not follow the Aufbau principle, there are some alternate ways that electrons can arrange themselves that give these elements better stability Using the Aufbau principle, you would write the following electron configurations Cr = [Ar] 4s^2 3d^4 Cu = [Ar] 4s^2 3d^9 The actual electron configurations are: Cr = [Ar] 4s^1 3d^5 Cu = [Ar] 4s^1 3d^10 To understand why this occurs ....
