The total energy of an electron in the second orbit of a hydrogen atom is −3.4eV. Using only this information, analyse the properties of the Li2+ ion (Z = 3) as follows.
(i) Find the total energy of an electron in the third orbit of the Li2+ ion.
(ii) Determine the radius of this orbit, expressing your answer in ångströms (Å).
(iii) Calculate the speed of the electron in this orbit as a fraction of the speed of light c.
