That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).When you heat something, the heat gives the atoms in the substance energy. What happens when electrons are excited? The energy goes to the electron which give it the ability to jump to the higher energy level. The electron moves faster and further away from the nucleus. What happens when electrons return to their ground state? energy is released.
