See Answer WebJan 30, 2024 · When considering the core electrons (or the electrons closest to the nucleus), the nuclear charge "felt" by the electrons ( Effective Nuclear Charge ( Z e f f )) is close to the actual nuclear charge. As you proceed from the core electrons to the outer valence electrons, Z e f f falls significantly.

Core electrons are the electrons in an atom that are not valence electrons and do not participate in chemical bonding. The nucleus and the core electrons of an atom form the atomic core. Core electrons are tightly bound to the nucleus. Therefore, unlike valence electrons, core electrons play a secondary role in chemical bonding and reactions by screening the positive charge of the atomic nucleus from the valence electrons.
