In a flame test, atomic-level changes in electron energy create macroscopic-level changes in visible light energy. Which statement about flame tests is true?(1 point)
Visible blue light corresponds to relatively small changes in the energy levels of the electrons.
Because the energy levels of the electrons in different metals are usually the same, different metals usually emit the same colors of visible light.
Because the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light. Lo
