Electropositivity
In: Chemistry
Right so, basically an inverse of electronegativity. See, atoms due to their geometry and charge, will have different strengths they hold onto or pull electrons towards them. The more distant you are from the positive core, the weaker the attraction, but also the weaker the repulsion from the electron shell. So, there’s a bit of a sweet spot, or some atoms simply produce geometry that has a more stable pull, basically. The general trend is that, the closer an atom is towards the right of the periodic table, the more electronegative it is, while the further down it is (bigger shells) the less electronegative it is. Electropositivity is the reverse of this.
Atoms like fluorine are very electronegative, thus they strongly pull on electrons, and energetically favor accepting them. Electropositive atoms like potassium, meanwhile, would favor *donating* them instead, because their pull is comparatively weaker.
