History

History
The element Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name from from Samarskite, the name of the mineral from which it was first isolated
The element Neon was discovered by Morris Travers in year 1898 in United Kingdom. Neon derived its name derived its name from from the Greek neos, meaning 'new'
