The negative ionic radius is larger than the neutral atomic radius
A full octet makes the noble gases nonreactive.
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
From the elements given, argon shows the least reactivity.
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
