Having a full octet of electrons makes an atom more stable. Among the noble gases, this stability increases as you move down the group due to the addition of electron shells. This results in increased atomic size and decreasing reactivity.
A full octet makes the noble gases nonreactive.
Radon has the highest boiling point among the noble gases. Its boiling point is -61.8°C, the highest among all noble gases.
Helium has the lowest ionization energy among noble gases.
The group of noble gases (Group 18) does not follow the normal trends seen in other groups on the periodic table. This is because they have full outer electron shells, making them very stable and unreactive compared to other elements.
Radon has the largest atomic radius among the noble gases due to the increased number of electron shells, causing the atoms to be larger in size.
