| Summary: | Cadmium (Gr. kadmeia - earth), a soft bluewhite metal, is a member of ~roup· II b of the Periodic Table, and lies between zinc and mercury. Cadmium (Cd) possesses the following physical constants: Atomic number 48; atomic weight 112.4; valency 2 and specific gravity a.?. The metal melts at 321°C and boils at ?65°c, and is remarkably volatile for a heavy metal. Its volatility has constituted a special industrial hazard since its b.p. is below the melting point of copper (1083°C), and copper-cadmium alloys were formerly difficult to prepare without gross losses of cadmium into the atmosphere. |
