Elements of the month - Scandium (Sc) & Helium (He)

2019-12-19

This year it's 150 years ago that Dmítriy Ivánovich Mendeléyev first published the Periodic Law that would later become the periodic table. Unesco has decided to celebrate this by calling 2019 "International Year of the Periodic Table of Chemical Elements" (IYPT).

Scandium and Helium is the 14th and 15th element in our series of elements found by Swedish researchers.

Scandium is a soft, lightweight, silver-shining metal that oxidizes slowly in air. The substance is mainly applied in alloys, which means that the substance is used in many different situations. From dentist treatments to Russian warplanes.

Scandium was first discovered by Professor Lars Fredrik Nilsson (in 1879) at Uppsala University on the basis of work done by Mendeleev. Using euxenite and gadolinite, Lars Fredrik Nilsson succeeded in isolating a new element that was consistent with Mendeleev's earlier discovery. Euxenite and gadolinite had so far only been found in Scandinavia, so Lars Fredrik Nilsson named the new element Scandium.

Helium is a colorless and odorless inert gas. The substance has the lowest boiling point of all elements, and only at high pressure does it become solid. Helium is also the second most common element in the universe.

It is used in a variety of areas, for example when some form of cooling is needed. But it is perhaps best known for being able to elicit a so-called "Donald Duck-voice" due to the high velocity of sound*.

*Warning: Never inhale pure helium, the oxygen saturation in the blood drops fast and there is a high risk of losing consciousness, on top of a risk of dying or suffer brain damage from oxygen deficiency.

Helium was first produced in 1895 by English and Swedish researchers, the Swedish part consisted of Per Teodor Cleve and Nils Abraham Langlet.

This will be the last entry in our series of elements found by Swedish researchers. It is quite impressive that a small country like Sweden found this many elements. A long tradition of chemistry research.

Merry Christmas & Happy New Years!
