Explanation

There are 6 noble gases in the periodic table: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They are in Group 18 (VIII A) and are characterized by their full valence electron shells, making them chemically inert. 92 is the approximate number of naturally occurring elements, 47 is silver's atomic number, and 500 has no periodic table significance.
