A doubly ionized atom of lithium Li 2+ is a hydrogen-like ion. When Li 2+ is in one of its excited states, its radius in this th state is the same as the radius of the first Bohr’s orbit of hydrogen. The atomic number of Li is 3.
Find the ionization energy for this state of Li 2+. Give your answer to three significant figures.
