Consider the behavior of ionization energies in the periodic table. Rank the effective nuclear charge Z* experienced by a valence electron in each of these atoms: atom Z* experienced by a valence electron. This creates a smaller atomic radius, higher ionization energy, and higher net positive charge on the atom. Due of a similar number of shielding electrons across a period, the valence electrons are pulled more tightly to the nucleus. System: Implications of Post-1957 Observations. Because chlorine is in the same period as phosphorus and sodium, but has the most protons in its shell (the most right within the same period) it has the greatest effective nuclear charge. 9: NIST-JANAF Thermochemical Tables, (Part I and Part, Nomenclature of Inorganic Chemistry: IUPAC Recommendations. The outer shell is #3. Ten electrons have a combined charge of -10. As you move from left to right along a period, and more positive charges (protons) fill up the nucleus, the more attraction the valence electron feels. effective nuclear chargeThat experienced by an electron in a multi-electron atom, typically less for electrons that are shielded by core electrons.

"Absolute Electronegativity and Hardness: Application to Inorganic Chemistry." Chemistry of the Periodic trends are important to understand how bonds are formed and how chemical reactions are produced. Berlin: SpringerVerlag, 1993. This is because, with increasing principal quantum number, electrons get further away from the nucleus creating a shielding effect felt by those electrons from the electrons closer to the nucleus. Periodic Trends Ionization Energy Worksheets, Effective Nuclear Charge and Nuclear Charge, Electrons in the same n group shield 0.35, except the 1s electron, which shield 0.30, Electrons in the (n-2) and lower groups shield 1.00, Electrons in the same n group shield 0.35, Electrons in the lower n group shied 1.00, 6 electrons are in n = 3 group: 6 x 0.35 = 2.1, 8 electrons are in the n = 2 group: 8 x 0.85 = 6.8, 2 electrons are in the n = 1 group: 2 x 1.00 = 2.
