One facet of the central field approximation for many-electron atoms is that inner-shell electrons screen the nuclear charge. To understand how this works quantitatively, first note that the probability distributions for electrons in different shells generally do not overlap much. For instance, the electrons in the M shell (n=3) are almost always farther from the nucleus than the electrons of the K (n=1) and L (n=2) shells. Thus, it is a good approximation to assume that the inner shells completely...

Repulsion of electrons within two interacting molecules produces changes in electron distribution. This change in electron distribution creates temporary dipole moments. Which of the following does this explain? Choose one or more: A. This explains why the dipole-dipole attractive force between dimethyl ether and acetone does not entirely account for the attractive force between these molecules. B. This explains why ammonia and nitrogen gas exhibit an attractive force between them. C. This explains how the molecules hydrogen fluoride and methanol...
