Consider a hydrogen-like ionized atom with atomic number

Z

with a single electron. In the emission spectrum of this atom, the photon emitted in the

n=2

n=1

transition has energy 74.8 eV higher than the photon emitted in the

n=3

n=2

transition. The ionization energy of the hydrogen atom is 13.6 eV. The value of

Z

is \_\_\_\_.
