SUMMARY
The slowest electron capable of exciting a hydrogen atom must possess a speed of 1.9 x 106 m/s. This conclusion is derived from the first excitation energy of the hydrogen atom, which is 10.2 eV, and the electron charge-mass ratio of 1.7 x 1011 kg-1. The calculations utilize the equations relating energy (eV), kinetic energy (1/2 mv2), and photon energy (hf).
