History

History
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name from from beryl, a mineral
The element Rhodium was discovered by William Hyde Wollaston in year 1803 in United Kingdom. Rhodium derived its name derived its name from from the Greek rhodos, meaning 'rose coloured'
