We’re being asked to determine if the given statement is true:
An electron in the 3s orbital is more shielded than one in a 2s orbital.
Recall that shielding is the resistance of an electron from the attractive forces exerted by the nucleus.
Determine whether each statement regarding penetration and shielding is true or false. (Assume that all lower-energy orbitals are fully occupied.)
An electron in a 3s orbital is more shielded than an electron in a 2s orbital.
