(A) The energy of an electron in the $n^{th}$ orbit of a hydrogen atom is given by the formula $E_n = -\frac{13.6}{n^2} \ eV$.For the ground state $(n=1)$,$E_1 = -\frac{13.6}{1^2} = -13.6 \ eV$.For the first excited state $(n=2)$,$E_2 = -\frac{13.6}{2^2} = -\frac{13.6}{4} = -3.4 \ eV$.The energy required for the transition is $\Delta E = E_2 - E_1 = -3.4 - (-13.6) = 10.2 \ eV$.
