If you pull a tomac radius versus first ionisation energy would the graph reveal a direct or inverse relationship

Inverse

Explanation:

Several facts are required to answer this question properly:

From the statements above, we may conclude that the greater the atomic radius (and, thus, the lower the attraction force between the valence electrons and the nucleus), the lower the ionization energy (due to the fact that a lower amount of energy is required to overcome a weaker force).

This means ionization energy is inversely proportional to atomic radius.
