History

History
The element Neon was discovered by Morris Travers in year 1898 in United Kingdom. Neon derived its name from from the Greek neos, meaning 'new'
The element Fermium was discovered by Lawrence Berkeley National Laboratory in year 1952 in United States. Fermium derived its name derived its name from from Enrico Fermi, physicist
