∙ 14y agoThe Element Scandium is defined as...
A silvery-white metallic element found in various rare minerals and separated as a by-product in the processing of certain uranium ores. An artificially produced radioactive isotope is used as a tracer in studies of oil wells and pipelines.
What are the origins of the word Scandium ?
Originates from the Latin word Scandia meaning " Scandinavia".
Scandium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. An Element classified as a Transition Metals is ductile, malleable, and able to conduct electricity and heat.
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.
Obtained from minerals thortveitile and wiikite in Scandinavia and Malagasy

An element that has some of the characteristics of metal is called?
A metaloid.
Is scandium in the human body?
Elemental scandium is not considered to be toxic. Little animal testing of scandium compounds has been done.[29] The median lethal dose (LD50) levels for scandium(III) chloride for rats have been determined and were intraperitoneal 4 mg/kg and oral 755 mg/kg.[30] In the light of these results compounds of scandium should be handled as compounds of moderate toxicity. or you can look up "scandium element" and go to wikipedia hope i helped :D
What is a slogans for scandium?
when you think of soft hair remember SCANDIUM
What is a better defensive lacrosse shaft the Brine Swizzle scandium or the Warrior Kryptolyte?
The Brine Swizzle Scandium is much better. It is an alloy mixed with scandium(some of the best stuff in the game). This combo allows it to be light but be very durable.
Is beryllium natural or man-made?
Scandium is a natural chemical element, a solid metal. Some applications are: - alloying component for aluminium - material for X-ray tubes (anticathode) used in X-ray spectrometry - component of some lasers - the oxide is used in high intensity lamps - the iodide is used in halogen lamps - etc.
How many electrons are in the scandium valence shell?
The element scandium has 21 electrons. However, most of these occupy the inner orbitals. The only electrons in the valence shell are those in the 2s orbital. Since there are two such electrons, scandium has 2 valence electrons.
