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.

In the parlance of chemists, metallic lead is electropositive.
-
In all groups of chemically similar elements the heaviest are the most electropositive.
-
Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.
-
That has the effect of making metallic lead less electropositive ie, more electronegative
-
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.
