The aim of this note is to ascertain the importance of the Fermi–Amaldi ( FA ) correction for the Thomas–Fermi ( TF ) theory of atoms. For this purpose, an analytic trial electron density has been chosen and the Thomas–Fermi–Amaldi ( TFA ) energy expression has been minimized by the Ritz method for the closed‐shell atoms Ne, Ar, Kr, Xe, and Rn. The variationally obtained electron densities have then been used for calculating the diamagnetic susceptibilities of these atoms. The calculated values show only a very small improvement over values calculated by Jensen by an analogous procedure from the TF energy expression.
