X-ray photoelectron spectroscopy is a method for detecting the presence of atoms on a surface.  In this method a high energy X-ray ionizes the molecule by kicking out a core electron (i.e. an electron from a 1s orbital).  Any excess energy leaves with the electron as kinetic energy. 

A. Calculate the kinetic energy in Joules of an electron ejected from a nitrogen atom using a 100 eV X-ray. (Hint: assume that nitrogen is just a hydrogen atom with a different nuclear charge)

B. Calculate the velocity of the electron in m/s.

C. Calculate the wavelength of the electron.
