Symbol: CrAtomic Number: 24Atomic Weight: 51.996Classification: shift metalPhase at Room Temperature: SolidDensity: 7.19 grams per centimeter cubedMelting Point: 1907°C, 3465°FBoiling Point: 2671°C, 4840°FDiscovered by: N.L. Vauquelin in 1797Chromium is the first element in the sixth obelisk of the routine table. That is classified together a transition metal. Chromium atoms have actually 24 electrons and also 24 protons with the most abundant isotope having actually 28 neutrons.Characteristics and PropertiesUnder standard problems chromium is a hard silvery metal with a bluish tint. When it is exposed come air a slim layer the chromium oxide creates over the surface ar which protects the metal from more reaction through the air. Chromium can be polished to achieve a shining mirror-like end up that is resistant come corrosion.For a metal, chromium is reasonably active and will reaction with countless other metals as well as with oxygen. It will not react with water.Chromium is recognized for the many vibrant compounds. These encompass chromium(III) oxide (green), command chromate (yellow), anhydrous chromium(III) chloride (purple), and also chromium trioxide (red).Where is chromium discovered on Earth?Chromium is only discovered rarely as a cost-free element in nature. That is mostly found in ores scattered transparent the Earth\"s crust wherein it is about the twenty-fourth many abundant element. The key ore that is mined because that the manufacturing of chromium is cromite.

How is chromium offered today?
Chromium is regularly mixed v other metals to do alloys. Among the most crucial chromium alloys is developed when chromium is combined with steel to do stainless steel. Stainless steel is strong and resistant come corrosion. Chromium is also used to develop superalloys through nickel the are offered in jet engines.Another well-known application because that chromium is as a shiny silver coating ~ above metallic surfaces. It additionally provides corrosion protection.Because chromium compounds come in such a variety of colors, it has also been provided as a pigment in paints. One of the most renowned colors made from chrome is yellow. Countless school busses space painted in chrome yellow.Other applications because that chromium include wood preservatives, tanning, together catalysts in commercial production, and also magnets.How was it discovered?Chromium was uncovered by French chemist Nicolas L. Vauquelin in 1797. He later on isolated the element and also gave that its name.Where go chromium obtain its name?Chromium it s okay its name from the Greek indigenous \"chroma\" an interpretation color. This surname was chosen since the aspect can form so countless different fancy compounds.IsotopesChromium has 4 stable isotope that take place in nature consisting of 50Cr, 52Cr, 53Cr, and 54Cr v the majority of the chromium uncovered in nature gift 52Cr.
Interesting Facts about Chromium
