✔ 最佳答案
a) Central atom I has 12 outermost shell electrons, thus it does not obey the octet rule.
b) Both atoms N and O has 8 outermost shell electrons, thus it obeys the octet rule.
c) Both atoms B and F have 8 outermost shell electrons, thus it obeys the octet rule.
d) Although atoms C and N obey the octet rule with 8 outermost shell electrons, atom H does not because it has only 2 outermost shell electrons, thus it is duplet but not octet.
