Use the periodic table to predict the most stable oxidation state for the following element: O
A) +1

D) -1
E) -2

Question

Quizplus · Accepted Answer

Oxygen is a non-metal, and its most stable oxidation state is -2. This is because oxygen is highly electronegative and tends to attract electrons towards itself when it forms bonds with other elements. In the vast majority of compounds, oxygen is found in the -2 oxidation state, such as in water (H2O) and carbon dioxide (CO2).
