Acute toxicity: Primary irritant effect: on the skin: Powder: irritant effect . 21) is a transition element but calcium (At. Scandium metal is used … Small amounts are alloyed into aluminum to improve strength, particularly at weld joints. Sensitization: No sensitizing effects known. Scandium is one of the two elements in the first transition metal period which has only one oxidation state (zinc is the other, with an oxidation state of +2). That means it has relatively low density, about 2.98g/cm 3. Scandium is known as one of the rare earth elements. Scandium metal: Scandium is a very light elemental metal that is often found alongside the rare earth elements. What is another name for the rare-earth...
