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 Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name derived its name from from the Latin silex, 'flint' (originally silicium)
