The correct electron configuration for ₁₇Cl is A) 1s²2s²2p⁵ B) 1s²2s²2p⁶3s² C) 1s²2s²2p⁶3s²3p⁵ D) 1s²2s²2p⁶3s²3p⁶4s²3d⁵

Question

Quizplus · Accepted Answer

- Each element in the configuration should be separated by a space or a comma. 
- The electron configuration should go in order from lowest to highest energy levels and sublevels.

Applying these rules to the choices, we can eliminate A and B because they do not have the correct order of energy levels and sublevels.

Choice D has too many energy levels and sublevels, which is unlikely for this molecule.

Choice C has the correct order of energy levels and sublevels and the correct number of electrons. Therefore, the best choice is C.
