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 Tellurium was discovered by Franz-Joseph Müller von Reichenstein in year 1783 in Romania. Tellurium derived its name derived its name from from Latin tellus, meaning 'earth' |
