Neon for UI stuff is simply a reference to neon signs being brightly coloured and attracting the attention of people to tell them stuff, and Fluorine for gatewaying to the outside world because Fluorine has a very electronegative ion that binds aggressively to other atoms.

Here electropositive copper combines with electronegative oxygen but in a way that leaves the combination slightly electropositive, whereas electropositive sulphur combines with oxygen in a way that leaves the combination slightly electronegative.

If zinc has an affinity for oxygen, it must be because the zinc is either electropositive or electronegative to oxygen.

If it has a greater affinity for oxygen than copper has, then the zinc must be either electropositive or electronegative to copper.

That makes lead dioxide much more electronegative than classical theory would predict.
-
However, although the properties of these basic chemical reactions have been measured and understood to the nth degree, no one has been able to show from first principles exactly why lead and lead dioxide tend to be so electropositive and electronegative.

That has the effect of making metallic lead less electropositive ie, more electronegative
-
Lead dioxide, on the other hand, is highly electronegative, preferring to absorb electrons in chemical reactions.
