History

History
The element Strontium was discovered by William Cruickshank (chemist) in year 1790 in United Kingdom. Strontium derived its name from from Strontian, a small town in Scotland
The element Tellurium was discovered by Franz-Joseph Müller von Reichenstein in year 1783 in Romania. Tellurium derived its name derived its name from from Latin tellus, meaning 'earth'
