Cobalt Definition Facts Symbol Discovery Property Uses Cobalt (co) lies with the transition metals on the periodic table. the atomic number of cobalt is 27 with an atomic mass of 58.933195. cobalt was first discovered in 1735 by george brandt in stockholm sweden. it is used in many places today, such as, magnets materials, paint pigments, glasses, and even cancer therapy. Cobalt (co), chemical element, ferromagnetic metal of group 9 (viiib) of the periodic table, used especially for heat resistant and magnetic alloys. the metal was isolated (c. 1735) by swedish chemist georg brandt, though cobalt compounds had been used for centuries to impart a blue colour to glazes and ceramics.
Cobalt Co Element Properties Amazing Uses Facts Cobalt is a chemical element; it has symbol co and atomic number 27. as with nickel, cobalt is found in the earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. the free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal. Cobalt is an essential trace element, and forms part of the active site of vitamin b12. the amount we need is very small, and the body contains only about 1 milligram. cobalt salts can be given to certain animals in small doses to correct mineral deficiencies. in large doses cobalt is carcinogenic. This chapter aims to collect and summarize the chemical properties of cobalt and some new cobalt compounds. it deals with the progress of cobalt chemistry. cobalt has been substantial in both chemical reactions and within many compounds. some of them are heterocyclic reactions, cobalt based catalyst and cobalamin. also, it discusses variety of applications of cobalt in a wide range of areas. Introduction. cobalt is a hard, metallic element symbolized as co with an atomic number of 27. this transition metal is crucial for various applications, such as rechargeable batteries, superalloys, and pigments. as a metal, it is solid at room temperature, silvery blue in color, and has magnetic properties.
