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]
Howard (surname) Howard is a common English language surname. Its origins are unclear. One theory is that it derived from the Norman-French personal name "Huard" or "Heward" adapting after the Norman Conquest of 1066. Another theory is that its origin may be pre 7th century Germanic from the personal name "Hughard" (prefix hug, meaning "heart"/"spirit"; suffix hard, meaning "hardy"/"brave"). Yet another theory is that the surname derived from the Anglo-Scandinavian personal name "Haward" (prefix ha, meaning "high"; suffix varthr, meaning "guardian"). The first public record of the surname is dated 1221 in Cambridgeshire. There are several variant surname spellings.[1]
