Which element has the same number of valence electrons as bromine (Br)? (1 point) Responses selenium (Se) selenium (Se) chlorine (Cl) chlorine (Cl) krypton (Kr) krypton (Kr) potassium (K)

Answer 1

Bromine (Br) has 7 valence electrons. The element that has the same number of valence electrons as bromine is selenium (Se), which also has 6 valence electrons in its outer shell (as it is in the same group as bromine). However, chlorine (Cl) has 7 valence electrons, making it the correct response.

Thus, the correct answer is selenium (Se).
