Predict the charge of the most stable ion of potassium.

Question

Quizplus · Accepted Answer

Potassium (K) belongs to Group 1 (alkali metals) of the periodic table, which means it has one valence electron. In order to achieve a stable electron configuration, it is energetically favorable for K to lose one electron and form a cation with a 1+ charge. Therefore, the most stable ion of potassium has a +1 charge, making choice (E) the correct answer. Choices (A), (B), (C), and (D) are all incorrect because they do not correspond to the charge of the most stable ion of potassium.
