Solution: Determine whether each statement regarding penetration and shielding is true or false. (Assume that all lower-energy orbitals are fully occupied.)An electron in an orbital that penetrates close to the nucleus tends to experience a higher effective nuclear charge than an electron in an orbital that does not penetrate close to the nucleus.

Problem

Determine whether each statement regarding penetration and shielding is true or false. (Assume that all lower-energy orbitals are fully occupied.)

An electron in an orbital that penetrates close to the nucleus tends to experience a higher effective nuclear charge than an electron in an orbital that does not penetrate close to the nucleus.

Solution

We have to determine whether the given statement regarding orbital penetration and shielding is true of false.

“An electron in an orbital that penetrates close to the nucleus tends to experience a higher effective nuclear charge than an electron in an orbital that does not penetrate close to the nucleus.”


Let’s start with the definitions of shielding and orbital penetration.


Shielding effect is the decrease in attraction between the nucleus and the valence electrons due to the presence of inner electrons (core electrons).
