The Element Scandium


"The Atom"

Definition of the Scandium Element
A silvery-white metallic element found in various rare minerals and separated as a by-product in the processing of certain uranium ores. Pure scandium is produced by heating scandium fluoride (ScF3) with Calcium metal. Scandium tarnishes in air and burns easily once it has been ignited. It reacts with water to form Hydrogen gas and will dissolve in many acids. An artificially produced radioactive isotope is used as a tracer in studies of oil wells and pipelines. The Atomic Number of this element is 21 and the Element Symbol is Sc.

Periodic Table Group and Classification of the of the Scandium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Scandium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

Facts about the History of the Discovery of Scandium Element
Scandium was discovered by Lars Nilson in 1879. Per Teodor Cleve discovered scandium oxide at about the same time as Nilson. In 1869 Dmitri Mendeleev, using his periodic law, predicted its existence and some properties of this element, which he called ekaboron, .
