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 ...

The symbol for atomic number 4 is Be. Element atomic number 4 was discovered by Louis Nicolas Vauquelin, who also discovered the element chromium. Vauquelin recognized the element in emeralds in 1797. Beryllium is an element found in beryl gemstones, which include emerald, aquamarine, and morganit...
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 ...
