Question
I. Arrange the following ions according to ionization energy, based on principles learned in lecture:
Na, Cl, Cs, C, K, Ne+, F, Ne
Your answer will be of the form A<B<C<D<E<F<G<H . Place the symbol for each atom or ion in the appropriate blank below:
____ < ____ <____ <____ <____ <____ < ____ < ____
1 2 3 4 5 6 7
Explain why Ne has larger or smaller ionization energy than Ne+. __________________________________________

II. Arrange the following ions according to expected size (radius), based on principles learned in lecture:
K, F+, Rb, Co25+, Br, Rb-, F, Mg
Your answer will be of the form A<B<C<D<E<F<G<H . Place the symbol for each atom or ion in the appropriate blank below:
____ < ____ <____ <____ <____ <____ < ____ < ____
1 2 3 4 5 6 7
Explain why F has larger or smaller radius than Mg. __________________________________________
Explanation / Answer
I Cs< K <Na <C <Cl <F <Ne <Ne+
The second ionization energy is always larger than the first ionization energy, because it requires even more energy to remove an electron from a cation than it is from a neutral atom
II Co25+ < F+ < F < Br < K < Rb < Rb-
