The effective nuclear charge of an atom increases with increasing atom number and with decreasing atomic radius as you go across a period. Part B Which of the choices below shows the correct ordering of K, Fe, Se, and Kr from largest atomic radius to smallest? 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. The Elements: Their Origin, Abundance and Distribution. The effective nuclear charge, Z eff, is the number of protons in a nucleus, Z, minus the screening constant, . It can be approximated by the equation: Z eff = Z S, where Z is the atomic number and S is the number of shielding electrons. Metallic character increases as you move down an element group in the periodic table. "Molecular Double-Bond Covalent Radii for Elements Li-E112." Edited by Richard W. Carlson. " /> (pick one) An atom of chlorine. Ihde, Aaron J. Mg =1s2 2s2 2p6 3s2 = [Ne]3s2, therefore magnesium has 10 core electrons from its 1s2, 2s2 . When atomic radius is small, the valence electrons are held more tightly to the nucleus resulting in a larger ionization energy. An atom of chlorine is larger than sulfur because the addition of an electron increases the repulsions without an increase in attraction for the nucleus resulting in less screening. The size of fluorine atoms is smaller than the size of sodium atoms because the effective nuclear charge is larger in fluorine than in sodium. The effective nuclear charge is always less than the actual nuclear charge [3]. (pick one) v An atom of sodium. Put Your Money On Me Music Video, a.
