Answer:
When an atom absorbs energy, the electrons move from their ground state to an Excited state. when an atom emits energy, the electrons move from an excited state to their ground state and give off energy(radiation).
Explanation:
In An atom electrons sphere the positively charged nucleus in different energy orbits.
The low energy orbits present near the nucleus and high energy orbits are farther from the nucleus. when an electron absorbs energy it becomes excited and jumps to a high energy state and when it loses energy as the radiation it gets back to its ground state or low energy state.
