Journal of the American Chemical Society, volume110, number13, 1988, pp41824186. Since all three atoms and ions had the same electron configuration and number of shielding electrons, the greater effective nuclear charge can be determined by the larger atomic number. Ronald Prasad. "Scheele's Priority for the Discovery of Oxygen." A given electron does not experience a full nuclear charge because the other electrons are sometimes between it and the nucleus and shield it from the nucleus. Effective nuclear charge can also be calculated using the following formula: In this formula Zeff represents the effective nuclear charge, Z represents the atomic number, and S represents the number of shielding electrons. An increase in atomic number with a constant shielding effect and decreasing atomic radius means the valence electrons are held more tightly to the nucleus and will result in a larger ionization energy and larger net positive charge for the atom. See abstract, Bearden, J. Metallic character increases as you move down an element group in the periodic table. "Thermal Conductivity of the Elements: A Comprehensive Review." Table A shows data as evidence for this trend by looking at electron penetration, or the ability of an electron to get close to the nucleus, of selected atoms broken down by their s and p subshells within the same energy level.
