The total energy of electron in the ground state of hydrogen atom is $- 13.6 eV$ . The kinetic energy of an electron in the first excited state is:NEET 2007

Options:

Answer:

Solution:

Energy of $n^{th}$ orbit of hydrogen atom is given by $E_{n} = - \frac{13.6}{n ^{2}} e V$ for ground state $n = 1$ $E_{1} = - \frac{13.6}{12} = - 13.6 eV$ for excited state $n = 2$ $E_{2} = - \frac{13.6}{22} = - 3.4 eV$
