In Lithium, 2s electron experience the force of attraction exerted by the nucleus is less than the actual charge of +3.
The electrons in an atom shield each other due to the pull of the nucleus. This effect is called the shielding effect.
This effect shows that the more the electron shells present in the atom, the more will be the shielding effect experienced by the outermost shell electrons.
Hence, option (3) is correct.
