### Ionization Energies of a Particular Element

#### Use the data table for the first eight ionization energies of a particular element shown below to predict and explain which element you would expect to show this trend in successive ionization energies.

| Ionization Number | Ionization Energy (kJ/mol) |
|-------------------|----------------------------|
| 1st               | 1,314                      |
| 2nd               | 3,388                      |
| 3rd               | 5,300                      |
| 4th               | 7,469                      |
| 5th               | 10,990                     |
| 6th               | 13,327                     |
| 7th               | 71,330                     |
| 8th               | 84,078                     |

Possible elements to consider:
1. Fluorine
2. Oxygen

#### Explanation:
1. **Core Electrons vs. Valence Electrons**: Core electrons are more strongly attracted to the nucleus than valence electrons. This stronger attraction increases the ionization energy significantly once all valence electrons have been removed and core electrons start to be ionized.
   
2. **Valence Electrons**: Valence electrons release more energy when they are removed from the atom, increasing the ionization energies as successive electrons are removed. This trend is reflected by the substantial jump in ionization energy between the 6th and 7th ionizations, indicative of removing core (inner-shell) electrons.

### Diagram/Graph Analysis:
This table presents a classic trend in ionization energies where the removal of valence electrons is followed by a dramatic increase in required energy for inner-core electrons, demonstrating the significant hold the nucleus has on core electrons as compared to valence electrons.
