Web5 mei 2024 · The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. The trend observed in size of ionic radii is due to shielding of the outermost electrons by the inner-shell electrons so that the outer shell electrons do not “feel” the entire positive charge of the nucleus. WebSi can be either a +4 or -4 ion, depending on what it's bound to. My question is for the -4 form. Si^-4 has an effective nuclear charge (Zeff) of +4 (14 protons - 10 core electrons), and 6 valence electrons. P^-3 has a Zeff of … chinaroller forum
