![]() ![]() ![]() However it is a little more complex than that.īecause elements have many shells, an electron may jump back in more than one hop giving off several different colours. ![]() So in general, a larger element would give higher energy photons off in a flame test. More protons => more attraction to electrons => more energy required to 'knock' up to a higher shell => higher energy/frequency photons. ( Lower energy Infrared -> ROYGBV -> UltraViolet -> X-rays Higher Energy)Īn element with more protons has a 'deeper' bottom shell. The further it 'drops' the higher energy/frequency/ colour it has. The electron which dropped down a shell has a lower energy state, so to conserve energy, a photon is emitted. The colours you get in flame tests / burning metals, comes from the electrons in one shell being 'knocked' (by the heat), into a higher shell then shortly after the electron 'drops' back (in one or more steps). ![]()
