- **Ionization Energy Comparison**
- O- vs O2-
The ionization energy of O- is less than that of O2-. This is because O- has one less electron than O2-, making it easier to remove an electron from O- as compared to O2-.
- Be+ vs Be
The ionization energy of Be+ is less than that of Be. This is because Be+ has already lost one electron, making it easier to remove another electron from Be+ as compared to Be.
- S vs P
The ionization energy of S is less than that of P. This is because S has one more electron shell than P, making it easier to remove an electron from S as compared to P.
