WebMar 6, 2024 · As the proton number increases, the nuclear charge increases as you move down a period. Notice that because valence electrons tend to lie so far away from the nucleus, the large separation would outweigh the high nuclear charges and in effect reduces the nucleus' electrostatic grasp on its valence electrons. WebOct 3, 2015 · The effective nuclear charge can be thought of the charge of the nucleus minus the charge of the core electrons. For an element such as fluorine, the nuclear charge is + 9 and the core electrons have a charge of − 2 so the effective nuclear charge is + 7. Similarly for carbon it would be + 6 − 2 = + 4. Now let’s assume a C − F bond.
