Problem

Four electrons are described below. I. A

1s

electron in

\text{Li}^{2+}

(Z=3)

II. A

2p

electron in Ne

(Z=10)

III. A

2p

electron in

\text{F}^{-}

(Z=9)

IV. A

3s

electron in Mg

(Z=12)

Which ranking orders these electrons from GREATEST to LEAST nuclear attraction? a)

\text{II} > \text{I} > \text{III} > \text{IV}

\text{I} > \text{IV} > \text{II} > \text{III}

\text{I} > \text{II} > \text{III} > \text{IV}

\text{II} > \text{III} > \text{I} > \text{IV}
