About Strontium

Strontium Metal Strontium is the chemical element with the symbol Sr and atomic number 38. 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 . It occurs naturally mainly in the minerals celestine and strontianite , and is mostly mined from these. Both strontium and strontianite are named after Strontian , a village in Scotland near which th...

Discoverer of Strontium

1. Adair Crawford Adair Crawford FRS FRSE (1748 – 29 July 1795 [1] ), a chemist and physician, was a pioneer in the development of calorimetric methods for measuring the specific heat capacity of substances and the heat of chemical reactions. In his influential 1779 book " Experiments and Observations on Animal Heat ", Crawford presented new experiments proving that respiratory gas exchange in animals is a combustion (two years after Antoine Lavoisier 's influential " On combustion in general "). Crawford also was involved in the discovery of the element strontium . 2. William Cruickshank (chemist) William Cruickshank (died 1810 or 1811) was a Scottish military surgeon and chemist, and professor of chemistry at the Royal Military Academy, Woolwich . William Cruickshank was awarded a diploma by the Royal College of Surgeons of England on 5 October 1780. In March 1788 he became assistan...
