Electronic Configurations Of Elements And The Periodic Table

Step 1: Electron configuration of O .
The molecular orbital configuration of O is: O has two unpaired electrons in the degenerate orbitals.
Step 2: Electron configuration of O .
In O , one electron is removed, leaving only one unpaired electron.
Step 3: Electron configuration of O .
In O , one additional electron is added, leading to two unpaired electrons.
Step 4: Electron configuration of O .
In O , two electrons are added, filling the orbitals and leaving no unpaired electrons.
Step 5: Conclusion.
O has the maximum number of unpaired electrons (two unpaired electrons).
