Detailed explanation-1: -The Scottish chemist William Ramsay (1852–1916) is known for work that introduced a whole new group to the periodic table, variously called over time the inert, rare, or noble gases.

Detailed explanation-2: -Using two different methods to remove all known gases from air, Ramsay and Rayleigh were able to announce in 1894 that they had found a monatomic, chemically inert gaseous element that constituted nearly 1 percent of the atmosphere; they named it argon.

Detailed explanation-3: -On This Day – March 23 : The first noble gas compound, xenon hexafluoroplatinate, was discovered on this day in 1962. Noble gases were thought to be completely inert, but English chemist Neil Bartlett observed that mixing platinum hexafluoride with xenon formed the yellow solid xenon hexafluoroplatinate.

Detailed explanation-4: -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.
