What is the correct electronic configuration for the ground state sodium atom,which has 11 electrons? A) 1s¹2s²3p⁶2s² B) 1s²2s¹3p⁶2s² C) 1s¹2s²2p⁶ D) 1s²2s²2p⁶3s² E) 1s²2s²2p⁶3s¹

Question

Quizplus · Accepted Answer

The correct electronic configuration for a ground state sodium atom is 1s² 2s² 2p⁶ 3s¹, which corresponds to choice E. Sodium has 11 electrons, and this configuration fills the 1s, 2s, and 2p orbitals completely, and places the last electron in the 3s orbital.
