A potassium atom has one valence electron in its outermost (fourth) energy level, and fluorine has seven valence electrons in its outermost (second) energy level. In order to obtain eight valence electrons (an octet), the potassium atom will transfer its single valence electron to the fluorine atom. This gives potassium eight … circle k monster truck bash discount tickets
