So this is the questions. Can I get some help with it?
An x-ray problem of wavelength 0.989 nm strikes a metal surface. The emitted electron has a kinetic energy of 969 eV (Conversion: 1 eV = 1.602 x 10-19 J). What is the binding energy of the electron in kj/mol? Remember, KE = 1/2 mv2. An Atomic emission spectrum of hydrogen shows three wavelengths: 121.5 nm, 102.6 nm, and 97.23 nm. Assign these wavelenghts to transitions in the hydrogen atom.
