Strontium - Element information, properties and uses ...

The Scottish village was called Strontian, the mineral found there, strontianite and the new element strontium. So, it seems there never was an eminent professor, Stront, commemorated by element number 38. Today, whenever you see a firework light up in brilliant crimson or a red flare smoking its way around a football stadium, you're looking at the light emitted from electrons transiting ...

Strontium was recognized as a new element in 1790 when Adair Crawford analyzed a mineral sample from a lead mine near Strontian, Scotland. Until then scientists had thought strontium and barium were the same element, and only barium’s existence had been recognized.. The mineral took its name from the Scottish town and was called strontianite (strontium

Strontium - Wikipedia

An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium.

Strontium Element Facts - Periodic Table of Elements and ...

Strontium is a soft, silvery metal. When cut it quickly turns a yellowish color due to the formation of strontium oxide (strontia, SrO). Finely powdered strontium metal is sufficiently reactive to ignite spontaneously in air. It reacts with water quickly (but not violently like the Group 1 metals) to produce strontium hydroxide and hydrogen gas.
