Metals have ionization energy value?

Explanation

Option: A Alkali Metals have low ionization energy because Size of the atom: The size of alkali metals is the largest in a particular period. As the size of the atom increases, the outermost electron moves far off from the nucleus and the nuclear attraction becomes weak. They can easily lose electrons and can become cationic. Option B : Non-metals have high ionization enthalpy due to their small size and high electronegativity as compared to metals. Option C is wrong because metals do have not intermediate ionization energy value. Option D is wrong because metals do not have a neutral ionization energy value.
