A reactive element with a relatively high electronegativity would be expected to have a relatively Group of answer choices small negative electron affinity and a relatively low ionization energy. small negative electron affinity and a relatively high ionization energy. large negative electron affinity and a relatively low ionization energy. large negative electron affinity and a relatively high ionization energy.

large negative electron affinity and a relatively high ionization energy.

Explanation:

In the periodic table, there are trends that appear to be somewhat complementary. A typical example is electro negativity and electron affinity. They actually refer to different things but they show exactly the same trend. They increase across the period and decrease down the group.

If an element has a high electro negativity, it must also have a high (large negative) electron affinity.

The other trend is ionization energy, the energy required to remove an electron from an atom. It increases across the period and decreases down the group. As the size of atoms become smaller across the period, both electron affinity, ionization energy and electro negativity increases. Hence the answer.
