🤓 Based on our data, we think this question is relevant for Professor Goodson's class at NOTRE DAME.
We’re being asked to rank the given elements by decreasing electron affinity.
Recall that electron affinity is the energy change from the addition of 1 e– to a gaseous element/ion.
It is represented by this chemical equation:
Atom(g) + e– → Ion–(g), ΔE = –E.A.
The trend for electron affinity is as follows: it increases from left to right and decreases down a period in the periodic table. The given elements are:
Rank these elements according to electron affinity.
