Answer» Helium (He), Z=2Neon (Ne),Z=10Argon(Ar), Z= 18 Krypton(Kr), Z=36Xenon(Xe), Z=54Radon(Rn), Z= 86YOU CAN REMEMBER THIS USING THE MEMONIC "Hema Ne Angrezi Ki Xerox Rakhvai" ☺ Zero group of Mendeleev\'s periodic table or the group\xa018\xa0of long form of\xa0periodic table is comprised of six elements and these eleements are called as inert gases as trhese elements do not react (inert) with other elements due to their octet outer electronic configaration which is stable configaration.
