Do the non-metallic character exhibited by the halogens have any relation to ionization enthalpy ?

Name the halogen having lowest ionization energy.

Why do alkali metals have low ionisation enthalpy?

Halogen with highest ionization enthalpy is ͟ ͟ ͟͟͟

Which of the following statements is incorrect in relation to ionization enthalpy?

Atoms of metals have only a few electrons in their valence shells while atoms of non-metals generally have more electrons in their valence shells. Metallic character is closely related to atomic radius and ionization enthalpy. Metallic character increases from top to bottom in a group and decreases from left to right in a period. Metallic character is inversely related to electronegativity. Considering the elements B,C,N and F the correct order of their non-metallic character is
