Interpretation: The terms ground state and excited state are to be explained. The result of an atom absorbing a photon is to be mentioned.
Concept Introduction:The concept behind the solution should be explained (including equations, formula, laws, theories, etc
Answer to Problem 3RQ
The ground state of an atom is the most stable state of atom in which it possesses the lowest amount of energy possible. If the atom is at any energy level higher than that of the ground state the atom is said to be in an excited state. On the absorption of a photon of energy the electron goes from the ground state to the excited state.
Explanation of Solution
On the absorption of a photon of energy, the internal energy of the electron will increase, and it will not be able to remain into the ground state energy level. Therefore, it goes from ground state to excited state.
