Cobalt
Cobalt is a brittle, hard, transition metal with magnetic properties similar to those of iron. Cobalt is present in meteorites. Main Ore deposits in the world are found in Zaire, Morocco and Canada. Cobalt-60 (60Co) is an artificially produced isotope used as a source of g rays (high energy radiation). Cobalt salts colour glass a beautiful deep blue colour. Cobalt was discovered in 1735 by the Swedish chemist George Brandt. It has a relatively low …showed first 75 words of 601 total…

…showed last 75 words of 601 total…similarities cobalt shares with some other metals are that it conducts electricity, it’s magnetic and it’s a strong metal, which can be used in machinery. The Differences it has are it can be artificially radioactive and that all cobalt atoms have 32 neutrons because 27 protons from mass number, which is 59, are 32. Cobalt also has one irregular feature, at normal temperature the conductivity of cobalt is below average but when heated the conductivity increases greatly.
