So how it chooses to form???

iron tends to be in Fe+3
its +3 oxidation state is more stable as its atomic no. is 26
so its configuration is
1s2 2s2 2p6 3s2 3p6 4s2 3d6
so after losing 1 electron it becomes stable as half filled and fully filled orbitals are more stable becoz they are more symmetric and can exchange energy.

Depends on the question. It can be either in the form of Fe2+ or Fe3+

Its Fe3, as in 2 Fe ions and 3 Oxygen ions which form rust, the most common molecule for iron molecules.

Depends on what the ionic compound is. I think Fe2+ but in like FeCl3.....that means theres a Fe3+ + 3Cl-

I suppose you could say Fe2+ is more common, however, it really depends on what iron combines with as to which ion will be used.
