Second answer.

Iron loses 3 electrons per atom, oxygen gains 2 per atom (and is thus reduced).

They turn into #Fe^(3+)# and #O^(2-)#, that combine in a 2:3 ratio to form #Fe_2O_3#

Note:
The very old definition of being oxidized was "binding with oxygen". Now the definition is a lot wider: "losing electrons".
