when energy is given to an atom, its electrons absorb that energy and jump to a higher shell.

this is called an excited state, but it is not stable.

1. - after a very short time, the electrons fall back down to their normal shells.

   - when they fall, the electrons release the extra energy they had absorbed.

   - this energy comes out as light.

   - the color of the light depends on how much energy is released when the electrons move down.

   - small amounts of energy give red or orange light.

   - larger amounts of energy give blue or violet light.

   - every element has its own energy levels, so each gives a different color of light.

   - for example: sodium gives yellow, copper gives blue-green, and strontium gives red.

   - in fireworks, this process happens when heat excites the metal atoms and their electrons fall back, producing different colors.

   - in hot metals like iron, the glow comes from heat radiation, not electron jumps. the color changes from red to yellow to white as the temperature increases.
