"It gains and loses electrons."
Explanation: Disproportionation (a dismutation) is a redox reaction in which the same chemical species is simultaneously oxidized and reduced — part of it loses electrons and part of it gains electrons. It does not have to be oxygen or have oxidation number 0. Example: 2 H2O2 → 2 H2O + O2 (O in H2O2 is both reduced to -2 and oxidized to 0).
