1 answer

Bromine (Br) is in Group 17 of the periodic table, which is also known as the halogens. Elements in the same group have the same number of valence electrons. Bromine has 7 valence electrons.

Other elements in Group 17 that have the same number of valence electrons (7) as bromine include:

  • Fluorine (F)
  • Chlorine (Cl)
  • Iodine (I)
  • Astatine (At)

So, any of these elements has the same number of valence electrons as bromine.
