The atomic core refers to an atom without valence electrons. The atomic core has a positive electric charge called the core charge and is the effective nuclear charge experienced by an outer shell electron. In other words, core charge is an expression of the attractive force experienced by the valence electrons to the core of an atom which takes into account the shielding effect of core electrons. Core charge can be calculated by taking the number of protons in the nucleus minus th…

Since these electrons reside at inner locations of the atom, the core electrons do not participate in bond formation. They reside in inner shells of an atom.

WebMay 1, 2024 · Solution. Each species has 10 electrons, and the number of core electrons is 2 (10 total electrons - 8 valence), but the effective nuclear charge varies because each has a different atomic number (Z). The approximate Zeff can be found with Slater's Rules. For all of these species, we would calculate the same sigma value: WebValence electrons are the farthest from the positive charge (the protons) and thus tend to be easier to remove than core electrons; this means that it takes them less energy to move far away from the atom. This difference comes from the electric force being an inverse square law. In addition, core electrons in the inner shells have lower energy ...
