  • An atom of hydrogen has only one electron so it gives the simplest emission spectrum.
  • The atomic spectrum of hydrogen consists of seperate series of lines mainly in the ultraviolet, visible and infared regions of electromagnetic spectrum.
  • Only the Balmer series is in the visible region
  • When an atom is excited by absorbing energy, an electron jumps to a higher energy level. As the electron falls back down to a lower energy level, it emits energy in the form of electromagnetic radiation.
  • The emitted energy can be seen as a line in the spectrum because the energy of the emitted radiation is equal to the difference between the two energy levels in this electronic transition
    IE. It is a fixed quantity / quantum 
  • Electronic transition is when an electron moves from one energy level to another
  • Delta E = hf, electronic transmitions…
