Nilson noticed a gap in weight between calcium and titanium and predicted there was an undiscovered element.
He then extracted scandium from euxenite. Nilson had already extracted erbium oxide and obtained ytterbium, then extracted another oxide that was a lighter element. This showed up as an unknown metal, that was then classified as scandium.

No scandals, just shine, with Scandium!

~The element gets its name from the word "Scandia", the Latin word for Scandinavia

~It is the main component of the rare mineral thortveitite, found in Scandinavia

~Scandium Can be a threat to the liver if accumulated in the human body, so don't let it get there

Scandium is typically used for research purposes.
Scientists say it has great potential because it has almost as low density as aluminum, but with a much higher melting point.
An alloy of scandium and aluminum is commonly used in baseball bats, bicycle frames, and certain Russian fighter planes (great timing on that one).

Just wanted to note- on the Thomas Jefferson In-Text Citation, I went through the website and it said to use that as the author. Just wanted to clarify in case it looked like the wrong citation.
