Electrons in atoms: energy levels, electron configuration and light
Main lesson
Configurations of ions
Use this for an ion’s configuration, such as Fe³⁺: electrons taken from the highest shell first.
A line in hydrogen’s spectrum
Use this for the energy and wavelength of the light a hydrogen atom gives off when its electron drops a level.
A photon’s frequency and energy
Use this for the frequency and energy of a photon from its wavelength.
