History
History |
The element Rhodium was discovered by William Hyde Wollaston in year 1803 in United Kingdom. Rhodium derived its name from from the Greek rhodos, meaning 'rose coloured' |
The element Rhenium was discovered by Masataka Ogawa in year 1925 in Germany. Rhenium derived its name derived its name from from Rhenus, the Latin name for the river Rhine |
