How does "electron affinity" change across the Periodic Table?

Jul 10, 2017

If we discount the Noble Gases, then electron affinity should INCREASE across the Period from left to right as we face the Table....

Explanation:

We assess the thermodynamics of the reaction........

$\text{Element(g)"+e^(-) rarr"Elemental anion(g)} + \Delta$

And $\Delta$ is the $\text{electron affinity}$.

Does this data set support my argument? Why or why not?
