Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
Radon is the largest noble gas element in terms of atomic size.
Helium, Neon, Argon, Krypton, Xenon, Radon, Ununoctium.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
The other so called "inert" or "noble" gases: helium, argon, krypton, xenon, radon.
A noble gas is an element found in group 18 of the periodic table. They are helium, neon, argon, krypton, xenon, and radon.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
The noble gases, which are helium, neon, argon, krypton, xenon, and radon, have their outermost electron shells full.
There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn)
The element with the densest noble gas is radon (Rn). It is a radioactive noble gas that is heavier than the other noble gases, making it the densest.
The odd element in the noble gases is xenon (Xe). It has an odd number of protons and neutrons in its nucleus, unlike the other noble gases (helium, neon, argon, krypton, radon) which have an even number.
The element, Radon is one of the Noble Gases like Helium and Neon that do not form compounds. Thus Radon is always found in the Pure State.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
