Radon is a non metal element. There are 86 electrons in a single atom.
Radon has six electron shells.
The number of electrons in the shells around a radon nucleus are: 2, 8, 18, 32, 18 and 8.
Electrons per shell in the radon atom: 2, 8, 18, 32, 18, 8 .
The noble gases, which are helium, neon, argon, krypton, xenon, and radon, have their outermost electron shells full.
Inert gases

Inert gases
Radon has 86 protons and electrons.
Radon has 86 protons (atomic number 86).
Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
Noble gases, or elements of the 18th group have full valence shells. In other words helium, neon, argon, krypton, xenon, radon and ununoctium have full valence shells.
