I was just wondering what atomic emission spectra are?

What are atomic emission spectra?

The electrons around any atom have a set of orbitals that represents the lowest energy state of that atom but there are a vast number of potential higher states with one or more electrons in excited states.  to raise the energy of an electron into one of these states requires the addition of a precise quantum of energy that is characteristic of the atom and the change of state.  This state will eventually decay to the normal lowest energy state emitting photons of electromagnetic radiation at specific frequencies that correspond to this energy change this produces an emission spectrum.  Conversely atoms may absorb energy from a continuum at these precise frequencies to get excited and create an absorption spectrum.
