Chromium symbol periodic table8/15/2023 The reserves of chromium are estimated at one billion tones, with unexploited deposits found in Greenland. Scientists estimate that the chromite deposits that have not been mined are far more than those which have. The other deposits are in countries like Kazakhstan, India, and Russia as well as the Philippines, Zimbabwe, and Finland. Around 40 percent of the chromite ores in the world are found in South Africa. At the same time, this element is not mined in pure form – it is mined as chromite. Another popular application of the metal is in chrome plating.Ĭhromium is a relatively frequently found in the Earth's crust. The reason is that it makes steel highly resistant to corrosion and discoloration when it is mixed into it. Chromium plays a major role in the development and production of stainless steel. This element is a very hard metal and hence highly resistant to rust. In more recent times, chromium was also used to produce pigments. In the late 18th century, this element was discovered in the mineral crocoite, which was used as a dye. The Chinese used this element to coat weapons as far back as two millenniums ago. This is because many of the compounds of this element have vibrant colors. The name of this element comes from the Greek word "chroma", which actually means colour. Chromium is steely-gray in color, hard, and with a high melting point. They are molybdenum (Mo), tungsten (W), and seaborgium (Sg). The other elements in this group are transition elements. Chromium (symbol Cr, atomic number 24) is the first element in Group 6 of elements.
