Which of the following electron configurations represents an excited state of the indicated atom? A)Ne: 1s² 2s² 2p⁶ B)N: 1s² 2s² 2p³ C)P: 1s² 2s² 2p⁶ 3s² 3p² 4s¹ D)Na: 1s² 2s² 2p⁶ 3s² 3p² 3s¹ E)He: 1s²

Question

Quizplus · Accepted Answer

The electron configuration for phosphorus in option C has an additional electron in its 3p orbital compared to its ground state configuration (1s2 2s2 2p6 3s2 3p3). This indicates that the atom has absorbed energy and that an electron has been promoted from the 3p subshell to a higher energy level.
