Potassium [K] has the same number of valence electrons as bromine [Br]. Both potassium and bromine have 7 valence electrons.
Which one tho?
Apologies for the confusion. The correct answer is Chlorine [Cl]. Chlorine [Cl] and Bromine [Br] both have 7 valence electrons. Potassium [K], Selenium [Se], and Krypton [Kr] have different numbers of valence electrons.
