    Orbitals are filled in the lower energy orbitals first, then fill higher energy orbitals. The 3d orbitals have a slightly higher energy than the 4s orbitals. So because the 4s orbi...

    Here 4s orbitals becomes outermost orbital and considered as a highest energy level as comparison to 3d as you know n increases energy of orbital increases. So electrons is removed...

    in other way, We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. We know that the 4s electrons are lost first during ionisation. ...
