Abstract

An upper bound is given for the maximum number, Nc, of negative particles (fermions or bosons or a mixture of both) of charge -e that can be bound to an atomic nucleus of charge + ze. If z is integral then Nc<~2z. In particular, this is the first proof that H - is not stable. For a molecule, Nc<~2Z+K-1, where K is the number of atoms in the molecule and Z is the total nuclear charge.
