Answer to Question #279484 in General Chemistry for Thel

Question

Determine the electronic configuration of potassium using spdf notation and orbital notation and identify if it is paramagnetic or diamagnetic

Answer 1

The full electron configuration of Potassium (K) is 1s²2s²2p⁶3s²3p⁶4s¹. The abbreviated form - [Ar]4s¹ - means the electron configuration of Argon (Ar), plus one electron in the 4s orbital. Argon has 18 electrons. The one additional electron configuration completes the picture for 19 electrons of Potassium.
