The Facts of Chromium
Chromium atomic number 24 is a chemical element
Chromium is a hard, silvery metal with a blueish tinge.
•Rubies get their red colour from chromium and glass treated with chromium has an emerald green colour.
•Chromium is remarkable for its magnetic properties: it is the only elemental solid which shows antiferromagnetic ordering at room temperature (and below). Above 38 °C, it transforms into a paramagnetic state.
•Chromium is an essential trace element for humans because it helps us to use glucose. However, it is poisonous in excess. We take into our bodies about 1 milligram a day.
•Chromium, unlike metals such as iron and nickel, does not suffer from hydrogen embrittlement.
•Chromium in air is passivated by oxygen, forming a protective layer that is essentially a spinel that is a few atoms thick
