Which element has the same number of valence electrons as bromine (Br)?
(1 point)
• krypton (Kr)
• chlorine (CI)
• potassium (K)
• selenium (Se)
1 answer
Bromine (Br) is in Group 17 of the periodic table and has 7 valence electrons. The element that has the same number of valence electrons as bromine is chlorine (Cl), which is also in Group 17 and similarly has 7 valence electrons.
So the correct answer is chlorine (Cl).
