  • Come be in your elements with Exploratorium host and scientific raconteur Ron Hipschman. Follow tales of intrigue and invention, join in dynamic demonstrations, and uncover fascinating connections between individual elements and our collective human experience.
    A transition metal found mixed among rare earth elements, scandium is thinly scattered across the globe, and is considered expensive and difficult to obtain. Its existence was predicted by Dmitri Mendeleev, known as the father of the Periodic Table, in 1869. In his groundbreaking Periodic System, Mendeleev determined a gap between the atomic weights of calcium and titanium would be bridged by an unknown element he termed ekaboron. Lars Frederick Nilsen confirmed this prediction in 1879, naming his discovery for the Scandinavian Peninsula where it was found. Pure scandium was ultimately isolated in 1937.
    Alloyed with aluminum, scandium strengthens jet planes and high-end bicycle frames but is too costly (6.5 times the value of gold) for widespread applications. And although pure scandium is seldom seen, its compounds are used in film set lamps and stadium lights to simulate natural sunlight.

    Along the lines of the baseball bats (which would be better if made of scandium aluminum), you can also use it in tennis rackets. One of the reasons Scandium is rare is because Calcium has a magic number of protons so if it absorbs a neutron, you tend to get a relatively stable calcium nucleus or something that goes on to titanium. Or else it absorbs a helium nucleus and skips by scandium. I think Theodore Grey called it 'the first element you've never heard of.'

    Great video. Please check out Clean Teq and Scandium International. They are mining companies in Australia looking to develop scandium deposits for the auto and aerospace industries. The presentations on their websites are fascinating!

    Is the alum/scandium recyclable? Melt it down and reform?

      Certain cat species can recycle it by digestion.

    What about Smith & Wesson revolvers such as the 340PD or the 360PD?

    UPDATE: Scandium is used to make low pressure hydrogen fuel stores.This may be its future.

      What a great future. Why dont you just leave it alone

    Scandium-240$/gram, Gold 41$/gram for them its 6.5 times more?🤔

    Puts me to sleep, get to the point of Scandium Jesus H Christ . It is about this anyways, deviating from the purpose of this video and power point bro. God sake
