The non-metal is likely to be the oxidizing agent.


Oxidants accept electrons; dioxygen gas gives #O^(2-)# when it oxidizes something, i.e. accepts electrons. A reducing agent donates electrons.

Given this, elemental metals tend to be reducing agents, and oxidants tend to be non-metals. #Cl_2# gas is thus the most potent oxidant, as it accepts electrons to give chloride ions, #Cl^-#.
