Chromium is a transition metal that is known for its hardness, strength, and resistance to corrosion. With an atomic number of 24 and a symbol of Cr, it is found in nature in the form of ores such as chromite, which is used as a source of chromium for industrial applications. Chromium is commonly used in stainless steel, which is an alloy of iron, carbon, and other elements, including chromium, that is resistant to rust and staining.

Chromium’s unique properties also make it valuable in other areas such as aerospace alloys, where it is used in components that must withstand high temperatures and stress. Additionally, chromium compounds have a variety of industrial and commercial applications, ranging from pigments and dyes to tanning agents and electroplating. However, some forms of chromium can be toxic to humans and the environment, so its use is closely regulated.
