On the number of electrons that a nucleus can bind

TL;DR

This paper reviews results related to the ionization conjecture, which posits that a neutral atom can bind at most one or two additional electrons, exploring theoretical bounds and implications.

Contribution

It summarizes key findings on the ionization conjecture, highlighting progress in understanding the maximum number of electrons a nucleus can bind.

Findings

Neutral atoms bind at most two extra electrons

Review of theoretical bounds on electron binding

Implications for atomic stability

Abstract

We review some results on the ionization conjecture, which says that a neutral atom can bind at most one or two extra electrons.
