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 Germanium was discovered by Clemens Winkler in year 1886 in Germany. Germanium derived its name derived its name from from Germania, the Latin name for Germany |
