Consider the following statements.I. The attractive interactions of an electron increases with increase of positive charge (Ze) on the nucleus.II. Due to the presence of electrons in the inner shells, the electrons in the outer shell will not experience the full positive charge of the nucleus (Ze).III The effect will be lowered due to the partial screening of positive charge on the nucleus by the inner shell electrons.IV. The net positive charge experienced by the other electrons is known as effective nuclear charge Zeff e. The correct set of statement is/are
