Compare a 2.2eV photon with a 2.2 eV electron in terms of energy, rest mass, speed, wavelength, and momentum

The attempt at a solution

So...

E = (2.2eV) x (1.60 x 10^{-19}J/eV) = 3.52 x 10^{-19}J

Wouldn't 3.52 x 10^{-19}J be the energy for both the photon and electron? If so, wouldn't that make mass, speed, wavelength, and momentum equal for both particles?
