With the question, ``Can relativistic charged spheres form extremal black
holes?" in mind, we investigate the properties of such spheres from a classical
point of view. The investigation is carried out numerically by integrating the
Oppenheimer-Volkov equation for relativistic charged fluid spheres and finding
interior Reissner-Nordstr\"om solutions for these objects. We consider both
constant density and adiabatic equations of state, as well as several possible
charge distributions, and examine stability by both a normal mode and an energy
analysis. In all cases, the stability limit for these spheres lies between the
extremal ($Q = M$) limit and the black hole limit ($R = R_+$). That is, we find
that charged spheres undergo gravitational collapse before they reach $Q = M$,
suggesting that extremal Reissner-Nordtr\"om black holes pro...
