Question

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)**.
