Cobalt: Properties, Uses, and Discoveries in the World of Transition Metals

Cobalt, discovered by Georg Brandt, is a transition metal with the atomic number 27 and symbol Co. It has a metallic gray appearance and an atomic mass of 58.9332 g/mol. Cobalt's melting point is 1495°C, and its boiling point is 2927°C. It forms alloys with nickel and iron, known as "Alnico," and is widely used in the glass and ceramic industries due to its resistance properties. Cobalt is also employed in electrolysis plating, showcasing its versatility in various applications. For more details, visit references such as Wikipedia and Google Images.

  1. SCIENCE PROJECT HOMEWORK COBALT

  2. Cobalt was discovered by Georg Brandt. Cobalt is in the transition metal group. Its atomic number is 27. Its symbol is Co. Its atomic mass is 58.9332g/mol.

  3. Its colour is metallic gray. • Its boiling point is 2927 celcius degree • Its melting point is 1495 celcius degree

  4. It joins with nikel and iron and then they product “Alnico” • Alcino is an Alloy

  5. Cobalt uses in glasses industry and ceramic industry. • Cobaltis resistant ,so it uses in electrolysis plating.
