History Strontium was named for the locality of the lead mine (Strontian, Argyleshire, Scotland) from which, in 1787, a previously rare mineral (strontianite, SrCO 3 ) was found in abundance. In 1790 Dr Adair Crawford reported on the medicinal properties of the 'muriated barytes' obtained ...
For these elements, the symbol usually refers to an older name that isn't used anymore. History of the Abbreviations There are eleven element abbreviations that don't seem to match their modern names. Those are subtle reminders of thehistory of the Periodic Tableand the process of the discover...
He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite ("The Element Strontium." It's Elemental). The discovery by Dr. Adair Crawford was the start of strontianite, but it was not the end of research on this element. Although Dr...
This change was accepted in America, but questioned in Britain because it did not conform to the -ium suffix precedent set by potassium, sodium, magnesium, calcium, and strontium (all discovered by Davy). Thus, the aluminium spelling became the most common in Britain. The United States ...
