WebArrange the following atoms in order of increasing effective nuclear charge experienced by the electrons in the n = 3 electron shell: K, Mg, P, Rh, and Ti. Rank the following atoms in order of effective nuclear charge, from lowest to highest: Na, Cl, Si, Al, S. Do not use Slater's rules to solve. Rank these elements according to electron affinity. WebThe shielding effect explains why valence shell electrons are more easily removed from the atom. The nucleus can pull the valence shell in tighter when the attraction is strong and less tight when the attraction is weakened. The more shielding that occurs, the further the valence shell can spread out. As a result, atoms will be larger.
