History

History

The element Argon was discovered by Lord Rayleigh in year 1894 in United Kingdom. Argon derived its name from from the Greek word argos, meaning 'idle'

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'
