Chemical properties-Cobalt is a moderately reactive element. It does not react with water at room temperatures. It reacts with most acids to produce hydrogen gas. It combines slowly with oxygen but does not catch fire and burn unless it’s in a powder form. Its melting point is 2,723 degrees F, boiling point is 5,198 degrees F

Physical properties-Cobalt is a shiny hard metal, conducts electricity, solid, blue
