Concerning the electron configuration of sulfur, 1s²2s²2p⁶3s²3p⁴, which of the following represents the core electrons only A) 1s² B) 1s²2s² C) 1s²2s²2p⁶ D) 1s²2s²2p⁶3s² E) 3s²3p⁴

Question

Quizplus · Accepted Answer

Core electrons are those in the inner shells of an atom, not involved in bonding. For sulfur (S), the core electrons are represented by its electron configuration excluding the valence electrons (in the 3s and 3p orbitals). Thus, the correct answer includes the 1s, 2s, and 2p orbitals fully filled, which corresponds to the configuration of neon (Ne), the nearest noble gas preceding sulfur in the periodic table.
