Among noble gases,gas of highest density is
He
Kr
Xe
Rn

Which of the followng noble gases has the highest positive electron gain enthalpy ?

Among noble gases, Xe is quite reactive and form a number of fluorides and oxyfluorides. In these compounds the electrons, from 5p orbitals are excited to 5d orbitals. The predicted shapes of xenon fluorides are linear, square planar and distorted octahedron. The shapes of xeon oxyfluorides can be prodicted by VSEPR theory.

The noble gas with highest ionization energy is

Statement I : Noble gases have highest ionization energies in their respective periods. Statement II : The ns-np of outermost shell of noble gases is completely filled.

A : Noble gases have highest ionization energies in their respective periods . R : The outer most sub-shell of noble gases in which electron enters is completely filled .

Among noble gases, only xenon reacts with flourine to form stable xenon fluorides, because xenon
