Use the periodic table to predict the most stable oxidation state for the following element: Pb
A) +1
B) +2
C) +3
D) -1
E) -2

Question

Quizplus · Accepted Answer

Looking at the periodic table, Pb is in Group 14, which means it has 4 valence electrons. Pb commonly exists in the +2 oxidation state, as it can lose its 2 valence electrons to form a stable ion with a noble gas electron configuration. While it is possible for Pb to form ions with different oxidation states, the +2 state is the most stable and commonly observed.
