What are the noble gasses and how many valence electrons do they have?

Noble gases are a group of chemical elements found in Group 18 of the Periodic Table, including helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are characterized by having a full outer shell of electrons, which means they possess eight valence electrons, except for helium, which has two. This full valence shell makes noble gases highly stable and largely unreactive under normal conditions.
