Define core of atom
WebNov 10, 2024 · The atom with labeled subatomic particles. The properties of protons, neutrons, and electrons hold atoms together. The nucleus of an atom is positively charged because its protons are positive and ... 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…
