Question

What is the general electron configuration for noble gas atoms?

Answer 1

Electrons configuration shorthand of the noble gases:

$He=1s^2$

$Ne=\left[He\right]2s^{2}2p^6$

$Ar=\left[Ne\right]3s^{2}3p^6$

$Kr=\left[Ar\right]4s^{2}3d^{10}4p^6$

$Xe=\left[Kr\right]5s^{2}4d^{10}5p^6$

$Rn=\left[Xe\right]6s^{2}4f^{14}5d^{10}6p^6$
