    As one considers orbits with higher values of n in a hydrogen atom, the electric potential energy of the atom
    (a) decreases
    (b) increases
    (c) remains the same
    (d) does not increase
    digAnsr:   b
    Ans : (b) increases
    The electric potential energy of hydrogen atom with electron at the nth state is given by
    `` V=-\frac{2\times 13.6}{{n}^{2}}``
    As the value of n increases, the potential energy of the hydrogen atom also increases, i.e. the atom becomes less bound as n increases.
