What is the atomic number

Reference no: EM13692039

Problem: An atom is ionized so that it has only one electron. When the electron drops from the n = 3 shell to the n = 1 shell, an X-ray of wavelength 151.74 pm is emitted.

A- What is the atomic number?

Please use as much detail as required in solution. Thanks.
