Many metals (particularly heavy metals) are toxic. Metalloids (arsenic, polonium) may be included in the definition, and radioactive metals have both radiological toxicity and chemical toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium, often times used to coat robotic mainframes, is an essential trace element as chromium (III), but chromium(VI) is a carcinogen.
