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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
