Valency electron

Dear All,

Fe has 26 electron,shell configuration is 2,8,14,2. The outer most shell has 2 valency electron ,so Fe 2+ . A well as Fe also have 3 valency electron by removing one paired electron from 3d6 and become 3d5, so already we have 2 electron in outermost shell now we received another one electron so now 3 electron in outermost shell , so Fe3+. My question is when 2 valency will exist and when 3 valency will exist,is their any condition? For example very Hot (approx 1000 deg c) Fe metal is (Ar)3d5, 4s3 and in normal ambient temperature Fe metal is (Ar)3d6,4s2 . Please confirm the same.

I think that while there is some influence of the energy available,
but the main influence is the nature of the other reactant(s).
