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 Gadolinium was discovered by Jean Charles Galissard de Marignac in year 1880 in Switzerland. Gadolinium derived its name derived its name from from Johan Gadolin, chemist, physicist and mineralogist
