Light metals are metals of low atomic weight. The cut off between light metals and heavy metals varies. Lithium, beryllium, sodium, magnesium and aluminium are almost always included. Additional metals up to nickel are often included as well. Metals heavier than nickel are usually called heavy metals. Light metals are generally less toxic than heavy metals. Beryllium is toxic, but it is rarely found in large concentrations. Vanadium, not always counted as a light metal, is also toxic. Other light metals are toxic in large amounts.de:Leichtmetalle eo:Malpezmetaloj ko:경금속 ka:მსუბუქი ლითონი ja:軽金属 pl:Metale lekkie sv:Lättmetall th:โลหะเบา zh:轻金属
