Bohr's Model for Hydrogen and Hydrogen Like Atoms

According to the Bohr Theory, among the following, which transition in the hydrogen atom will give rise to the least energetic photon?

The energy of the second Bohr orbit of the hydrogen atom is $-328 \mathrm{kJ} {\mathrm{mol}}^{-1}$. Hence, the energy of the fourth Bohr orbit would be

The radius of hydrogen atom in the ground state is  $0.53 \mathrm{\AA }.$  What is the radius of  ${\mathrm{Li}}^{2+}$  ion (Atomic number $=3$) in a similar state?

Calculate the neutron separation energy from the following data:
$\mathrm{m}\left({}_{20}{}^{40}\mathrm{Ca}\right)=39.962591\mathrm{u}$

$\mathrm{m}\left({}_{20}{}^{41}\mathrm{Ca}\right)=40.962278\mathrm{u}$
