Answer:
F1+ is the one that violates the octet rule
Explanation:
F1+ does not end up having 8 electrons in its valence shell, and there for violates the octet rule, for an atom to comply with the octet rule its charge must reflect the number of electrons it needs to gain or lose to make an octet, but F1+'s charge does not reflect the number of electrons it needs to be stable or have an electron configuration of a noble gas
Answer:
O
Explanation:
they have O valence electrons
