Quizplus · Accepted Answer

The core charge of an atom is the effective nuclear charge experienced by the valence electrons. It can be calculated as the total charge of the nucleus (the atomic number, which is the number of protons) minus the inner shell electrons. Silicon has an atomic number of 14 and has 10 electrons in the inner shells (2 in the first shell and 8 in the second shell), leaving a core charge of +4.
