The name of holmium is derived from the Stockholm which is capital of Sweden. * Holmium Rare Earth Element is a bright, soft and silvery white rare metal and holmium is malleable. * Holmium Rare Earth Element is measured to be slightly toxic. No serious harms in industrial usage have been detected. Holmium does not affect humans in terms of biological role, but Holmium’s salts are able to stimulate metabolism.   Actually, humans typically consume about a milligram of holmium a year. Plants do not readily take up holmium from the soil. Some vegetables have had their holmium content measured, and it amounted to 100 parts per trillion. * In dry air, holmium normally doesn’t react.
