WebAluminum is period three with a relatively large nuclear charge, and potassium is in period 4 with little attraction for the outermost electron. Therefore, potassium has the greatest atomic radius and oxygen has the smallest atomic radius. — increasing atomic r Continue Reading More answers below WebIn quantum chemistry, Slater's rules provide numerical values for the effective nuclear charge in a many-electron atom. Each electron is said to experience less than the actual nuclear charge, because of shielding or screening by the other electrons. For each electron in an atom, Slater's rules provide a value for the screening constant, denoted by s, S, or …

WebAll six of the ions contain 10 electrons in the 1 s, 2 s, and 2 p orbitals, but the nuclear charge varies from +7 (N) to +13 (Al). As the positive charge of the nucleus increases while the number of electrons remains the same, there is a greater electrostatic attraction between the electrons and the nucleus, which causes a decrease in radius. Web51 rijen · Isotopes of aluminium. Aluminium or aluminum ( 13 Al) has 22 known isotopes from 22 Al to 43 Al and 4 known isomers.
