What is the symbol for noble gas?
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

Why are noble gasses called noble?
The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass. They are called noble gases because they are so majestic that they do not react with anything in general. They’re also known as inert gases for this reason.

What is xenon gas?
xenon (Xe), chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colourless, odourless, and tasteless.
How do you write O2?
Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
Who discovered noble gas?
Sir William Ramsay
Sir William Ramsay, (born Oct. 2, 1852, Glasgow, Scot. —died July 23, 1916, High Wycombe, Buckinghamshire, Eng.), British physical chemist who discovered four gases (neon, argon, krypton, xenon) and showed that they (with helium and radon) formed an entire family of new elements, the noble gases.
