Strontium Metal

  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...

  I am Ajey M Katari  From Kensri school and this is my blog on  Chemistry And My element Is 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...
