As per the level of energy, electron filling in the shells would be 2, 8, 8, 18, 32. So, the compounds with Atomic Number 10, 18, 36, 54 would have completely filled orbitals. Hence, the elements are inert gases or zero group members. Noble gas are of the seven chemical elements that make up Group 18 (VIII) of the periodic table. The elements are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn), and Oganesson (Og). The noble gases are colourless, odourless, tasteless, nonflammable gases.
