where did the name noble gases come from
Noble gas Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann[1] to indicate their extremely low level of reactivity. The name makes an analogy to the term "noble metals", which also have low reactivity. The noble gases have also been referred to as inert gases, but this label is deprecated as many noble gas compounds are now known.[2] Rare gases is another term that was used,[3] but this is also inaccurate because argon forms a fairly considerable part (0.94% by volume, 1.3% by mass) of the Earth's atmosphere due to decay of radioactive potassium-40.[4]
Indian Institute of Science At the time of the inception of IISc in 1909, Morris Travers, Sir William Ramsay's co-worker in the discovery of the noble gases, became its first Director. For Travers, this was a natural continuation of his work on the Institute, since he had played a role in its founding. The first Indian Director was the Nobel Laureate Sir C.V. Raman. Raman was the Indian Science-based Nobel Laureate.[13] The current Director is Anurag Kumar.
