      Now consider an excited-state hydrogen atom. what is the energy of the electron in the n=4 level?

        For ground-state: n=1

        Energy, E
        = -2.18 x 10^-18 / n^2 J
        = -2.18 x 10^-18 / 1^2
        = -2.18 x 10^-18 J

        In energy level n=4

        Energy, E
        = -2.18 x 10^-18 / n^2 J
        = -2.18 x 10^-18 / 4^2
        = – 1.36 x 10^-19 J
