Answer is Iron.

Explanation:

The atomic number of Iron (Fe) is 26. SO the Electronic configuration is,

Fe = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d⁶

When Iron looses three electrons its electronic configuration becomes,

Fe³⁺ = 1s², 2s², 2p⁶, 3s², 3p⁶, 3d⁵

Result:

After loosing three electrons the d-shell get 5 electrons (Half-Filled D-Orbital) which is stable, Hence due to this stability Iron tends to attain + 3 charge.
