History
History |
The element Barium was discovered by Carl Wilhelm Scheele in year 1808 in United Kingdom. Barium derived its name from from the Greek barys, meaning 'heavy' |
The element Holmium was discovered by Marc Delafontaine in year 1878 in Switzerland. Holmium derived its name derived its name from from Holmia, the New Latin name for Stockholm |
