Quizplus · Accepted Answer

Potassium (K) is a group 1 metal, therefore it has one valence electron. To become stable, it will lose this electron to form a cation. The most stable ion will be the one with a noble gas electron configuration, which is achieved by losing one electron to form a 1+ ion. Therefore, the answer is E) 1+.
