In the context of excited atoms, briefly explain ground state
What will be an ideal response?
Atoms cannot exist in an excited state forever. The excited atom is unstable and must eventually (usually within 10-9to 10-6seconds) give up the energy it has absorbed and return its electron to a lower energy level. The lowest energy level an electron can occupy is called the ground state.
