9 Why does this happen?

10 Why does this happen? The electrons in the outer shell are “excited” by the energy received from the flame.

11 Why does this happen? The electrons in the outer shell are “excited” by the energy received from the flame. This causes them to be raised to a higher energy level.

12 Why does this happen? The electrons in the outer shell are “excited” by the energy received from the flame. This causes them to be raised to a higher energy level. When the electrons fall back to their normal energy levels, the extra energy is given off in the form of light.
