Which of the following is the correct ground state electron configuration for a magnesium atom? A)1s²2s²2p⁸ B)1s²2s²2p⁶3s² C)1s²2s¹⁰ D)1s²2s²2p⁶3s²3p² E)1s²2s²2p⁶3s¹

Question

Quizplus · Accepted Answer

The correct ground state electron configuration for a magnesium atom, which has 12 electrons, is represented by the notation that correctly follows the order of filling the electron orbitals: 1s^2 2s^2 2p^6 3s^2. This corresponds to choice B, which correctly fills the orbitals in the order of their increasing energy levels.
