Hydrogen is an unusual element because it behaves in some ways like the alkali metal elements and in other ways like nonmetals. Its properties can be explained in part by its electron configuration and by the values for its ionization energy and electron affinity.
(a) Explain why the electron affinity of hydrogen is much closer to the values for the alkali elements than for the halogens.
(b) Is the following statement true? "Hydrogen has the smallest bonding atomic radius of any element that forms chemical compounds." If not, correct it. If it is, explain in terms of electron configurations.
(c) Explain why the ionization energy of hydrogen is closer to the values for the halogens than for the alkali metals.
(d) The hydride ion is H-. Write out the process corresponding to the first ionization energy of hydride.
(e) How does the process you wrote in part (d) compare to the process for the electron affinity of elemental hydrogen?

These answers provided tell you about the behavior of Hydrogen in different regards like Ionization energy and Electron affinity. Sometimes they behave more like halogens and sometimes they behave more like Alkali elements. These properties depend upon the electronic configuration and nuclear force of attraction consequently. Hence, here I have sown the unusual nature of Hydrogen element.
