History

History
The element Cadmium was discovered by Karl Samuel Leberecht Hermann in year 1817 in Germany. Cadmium derived its name from from the New Latin cadmia, from King Kadmos
The element Argon was discovered by Lord Rayleigh in year 1894 in United Kingdom. Argon derived its name derived its name from from the Greek word argos, meaning 'idle'
