SUMMARY
An atom can become excited through collisions with other particles, such as atoms or molecules, under specific conditions of pressure and temperature. The energy of the collision must be sufficient to elevate an electron to a higher orbital. The excitation process is quantitatively described by the Boltzmann factor, which relates the temperature of the system to the likelihood of excitation. The Franck-Hertz experiment serves as a practical illustration of these principles in action.
