Using Slater's rule calculate the effective nuclear charge on a 3p electron in aluminium and chlorine. This is for your rules, where the core electrons contribute 1 to S and the valence electrons contribute nothing. The number of shielding electrons can be calculated by subtracting the number of valence electrons from the total number of electrons in the atom. It is possible to determine the strength of the nuclear charge by the oxidation number of the atom. Calculation and Conversion to Pauling Units." The actual nuclear charge is the atomic number multiplied by the proton charge. pp. As previously discussed, when an atom has a larger atomic radius, there is a larger shielding effect on its valence electrons.

This is for your rules, where the core electrons contribute 1 to S and the valence electrons contribute nothing. To predict relative ionic sizes within an isoelectronic series. "Atomic Radiative and Radiationless Yields for K and L. Origin of Elements in the Solar System: Implications of Post-1957 Observations. The effective nuclear charge, Zeff, for chlorine is approximately 2+. 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. And so therefore we would say that are effective nuclear charge of chlorine is equal to positive seven or plus seven. b) What is the effective nuclear charge (Zeff) of Chlorine (Cl)?

(1s) (2s, 2p) (3s, 3p) (3d) (4s, 4p) (4d) (4f) (5s, 5p) . 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. Sanderson, R. T. Simple Inorganic Substances. LandoltBrnsteinGroup VI Astronomy and Astrophysics. If you count all the other electrons (in shells #1 and #2), you find 10. d. An atom of sodium is smaller than an atom of magnesium because both effective nuclear charge increases down a group and the principal quantum number of the valence orbitals increases. Yaws, Carl L.
