we made experiment in our class and we found ot that when you burn:
Potassium Chloride is purple
Sodium Chloride yellow
Barium Chloride green
Calcium Chloride orange
Lithium Chloride red
And now comes the question:Why they have these colours when you burn them,it has something to see with particles and something like that,could someone explain it to me plizz

Each chemical element has electrons in different energy states around an atom. When heated, energy is absorbed causing the electron to become excited, but unstable. When the electron returns to its lower energy state (ie, as it cools at the top of the flame) the energy is released in the form of a photon(light). The energy of the photon determines the wavelength or colour.
