Detailed explanation-1: -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.
Detailed explanation-2: -Hydrogen is not a noble gas as it has one electron in its shell and it is not stable unlike noble gases which are having 2, 8, 8 electrons in their outer shell.
Detailed explanation-3: -Because they do not readily combine with other elements to form compounds, the noble gases are called inert. The family of noble gases includes helium, neon, argon, krypton, xenon, and radon.
Detailed explanation-4: -Detailed Solution. Hydrogen is not a noble gas. Any of the gaseous elements Helium, Neon, Argon, Krypton, Xenon, and Radon, occupying Group 0 (18) of the periodic table are noble gases as they are totally unreactive.
Detailed explanation-5: -Noble gases do not form any chemical bond.
