To add on, the elements are also arranged in order of electronegativity and atomic radius (among others, but those are the most important ones).

Ionization energy and electron affinity are there also, but I always look at them as a function of the first two I mentioned.

I guess there's also "metallic character" but that rarely is used (personally) for the type of chemistry I do.

You are correct in what you said though. Great comment.
