Question

Rank the following pairs of elements in terms of their electron affinities compared against each other. Note that larger (more positive) electron affinities refer to more exothermic electron affinities, as defined in the Tro textbook. All pairs must be correctly ranked for full credit. S vs. Al < K vs. Na < P vs. S < O vs. F.

2.

Select one:

The IE of Mg is higher than IE of Be

The IE of Mg is higher than IE of Na

The IE of Mg is lower than IE of Mg⁺

The IE of Mg is higher than IE of Ca

The IE of Mg is lower than IE of Ne

3. Rank the following atoms in order of increasing ionization energy, from lowest to highest: S, Se, O, Ne, He

4.
