I know that in chemical trends with the periodic table, shielding takes precedence over effective nuclear charge.
If I was told to arrange the elements Cl, Ar and K in order of increasing value for ionization energy, what is it? Would it be K the lowest (because shielding takes precedence), Cl second highest and Ar the highest? Ar is smaller than K (less energy levels) and is a noble gas.
