During change of O2 to O+2O2 to O2+ ion, the electron is removed from which one of the following orbitals?
Question
During change of O2 to O+2O2 to O2+ ion, the electron is removed from which one of the following orbitals?
Solution
The electron is removed from the 2p orbital. This is because oxygen has an electron configuration of 1s² 2s² 2p⁴. When it loses an electron to become O2+, it loses this electron from the highest energy level, which is the 2p orbital.
