Cobalt, represented by the symbol Co, is a chemical element known for its striking blue color in compounds. It is a hard, lustrous metal that is primarily used in the production of high-strength alloys and batteries, particularly in rechargeable lithium-ion batteries. Cobalt is essential for various industrial applications, including the manufacture of tools and catalysts.
In nature, cobalt is often found in combination with other elements, and it is primarily extracted from ores such as cobaltite and smaltite. The element plays a crucial role in the production of vitamin B12, which is vital for human health. Cobalt's unique properties make it a valuable resource in modern technology and industry.
