Hydrogen is an unusual element because it behaves in some ways like the alkali metal elements and
Question:
(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.
