History

History
The element Germanium was discovered by Clemens Winkler in year 1886 in Germany. Germanium derived its name from from Germania, the Latin name for Germany
The element Calcium was discovered by Humphry Davy in year 1808 in United Kingdom. Calcium derived its name derived its name from from the Latin calx, meaning 'lime'
