Demarcus Gilbert · Answer 1

K

Explanation:

The key aspect in this question is to look for Ionization Energy (EI), which describe the needed energy to take out an electron. Thefore, the potasiumm need lower energy. Another important thing is analyze how K will take nobel gas electron configuration when loss 1 electron, this It will be more stable
