(a) Equation can be used to calculate the change in energy when the electron
changes orbit.
(b) For n = 1, the electron has a more negative energy than it does for n = 6 which
means that the electron is more loosely bound in the smallest allowed orbit.
(c) The negative sign in equation simply means that the energy of electron bound to
the nucleus is lower than it would be if the electrons were at n4 n3 the
infinite distance from the nucleus.
(d) Larger the value of n, the larger is the orbit radius.
