For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the electrons more excited‚ allowing for the electrons to transition faster. Then‚ the method of lighting the
