Models of dynamical symmetry breaking suggest the existence of many particles in the 10 GeV to 100 TeV mass range. Among these may be charged particles, X^±, which are stable or nearly so. The X⁺'s would form superheavy hydrogen, while the X^-'s would bind to nuclei. Chemical isolation of naturally occurring technetium, promethium, actinium, protactinium, neptunium or americium would indicate the presence of superheavy particles in the forms RuX^-, SmX^-, {sup 232}ThX^-, {sup 235, 236, 238}UX^-, {sup 244}PuX^-, or {sup 247}CmX^-. Other substances worth searching for include superheavy elements with the chemical properties of B, F, Mn, Be, Sc, V, Li, Ne, and Tl.
