Respuesta :

Towards the extreme right of the periodic table is the group 18 which corresponds to the noble gases. Helium, Neon, argon, krypton and xenon. These gases have a completely filled outer or valence shell and have a general electronic configuration represented as: ns²np⁶. This fully filled configuration makes these gases extremely stable and inert.
