Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. The chemical symbol for Chromium is Cr. Chromium is a steely-grey, lustrous, hard and brittle metal[4] which takes a high polish, resists tarnishing, and has a high melting point.

Metals react directly with a number of elements, including oxygen, nitrogen and carbon. First we shall look at the reactions of metals with oxygen, to form oxides. Metal Oxides and Hydroxides Metal oxides are typically prepared by heating the metal in air. Most metal oxides and hydroxides are basic, and so

Chromiums density is 7.2 g/cm 3. Chromium is nonferrous. Production . Some metal alloys occur naturally and require little processing to be converted into industrial-grade materials. Ferro-alloys such as Ferro-chromium and Ferro-silicon, for instance, are produced by smelting mixed ores and are used in the production of various steels.

Classify each element below as metal, nonmetal, or metalloid. phosphorus (select) chromium (select) arsenic 2013-01-03 Common forms are chromium-0, which has no charge, chromium+3, which has an ionic charge of plus 3, and chromium+6, which has a charge of plus 6. Chrome metal (the form chromium-0) is the element that makes steel “stainless.” Chromium in this form is hard, stable, and resistant to chemical changes such as oxidation or rust.
