Maximum unpaired electrons in an atom

AI Thread Summary
The discussion focuses on determining the number of unpaired electrons in an atom with 13 electrons in the M shell and one in the N shell. The electron configuration is identified as 3s2 3p6 3d5 4s1, which corresponds to Chromium. Based on this configuration, the total number of unpaired electrons is calculated to be six. The analysis confirms that the configuration aligns with known principles of electron distribution in atomic shells. Understanding unpaired electrons is crucial for predicting an atom's magnetic properties and reactivity.
