    The Bohr's energy equation for H atom reveals that the energy level of a shell is given by \[E=-13.58/{{n}^{2}}eV\]. The smallest amount that an H atom will absorb if in ground state is

    A) \[1.0\text{ }eV\]

    B) \[3.39\text{ }eV\]

    C) \[6.79\text{ }eV\]          

    D) \[10.19\text{ }eV\]

    Correct Answer: D

    Solution :

    [d] The smallest value of energy of an electron in H atom in ground state can absorb is \[={{E}_{2}}-{{E}_{1}}\] \[=\frac{-13.58}{4}-\left( \frac{-13.58}{1} \right)=10.19\]
