The first ionization potential for S is lower than the first ionization potential for P because: A)Hund's rule is violated B)P has a p³ configuration C)ionization potentials decrease across a representative period D)P is to the right of S on the periodic table E)P is below S on the periodic table

Question

Quizplus · Accepted Answer

Phosphorus has a half-filled p^3 configuration, which is more stable, making it harder to remove an electron compared to sulfur, which has a p^4 configuration.

The First Ionization Potential for S Is Lower Than the First
