Could someone explain what the answer is? Don’t all of them have full valence shells?
is the answer E)?
by octet rule they mean are each atoms surrounded by 4 bonds or lone pairs of electrons so they have a valence of 8
correct options are D) an E) but since Br is n=in the third period it isn’t concerned with octet rule so i think E) is most appropriate
Thanks Juliette, it does make the most sense (there’s no mark scheme for this I believe)
