This is a Lewis structure example on my Chemestry book. But I
am very confused about the number of valence electrons in Iodine on
this specific structure: in general we try to achieve the octet
rule, but on this structure Iodine have 4 lone pairs and 4 single
bond. Since each single bond equals to 2 electrons, doesn't Iodine
have way too many electrons?
thank you
