The correct Answer is:
To solve the question regarding what happens when an electron is excited to the fourth energy level in an atom, we can break it down step by step. ### Step-by-Step Solution: 1. **Understanding Energy Levels**: - Atoms have different energy levels, denoted by the principal quantum number \( n \). The ground state corresponds to the lowest energy level (n=1), and higher energy levels are n=2, n=3, n=4, etc. 2. **Excitation of the Electron**: - When an electron is excited to the fourth energy level (n=4), it means that it has absorbed energy and moved from a lower energy level (like n=1, n=2, or n=3) to a higher energy level. 3. **Stability of Excited State**: - An electron in an excited state (like n=4) is not stable. It cannot remain in this state permanently because excited states are temporary. The electron will eventually return to a lower energy level. 4. **Return to Ground State**: - The electron can return to its original state (ground state or lower energy level) either in one jump or through multiple jumps. This means it can drop directly to the ground state or go down stepwise (for example, from n=4 to n=3, then n=3 to n=2, and finally n=1). 5. **Options Analysis**: - **Option 1**: "Remain there permanently" - This is incorrect because electrons cannot stay in excited states indefinitely. - **Option 2**: "Comes back to the original state either in one jump or more jumps" - This is correct as explained above. - **Option 3**: "Come back to ground state in one jump" - This is not necessarily true; it can also return in multiple jumps. - **Option 4**: "Rise to higher energy level" - This is incorrect because the electron is already at a higher energy level (n=4) and cannot rise further without additional energy. 6. **Conclusion**: - The correct answer is that the electron will come back to the original state either in one jump or more jumps. ### Final Answer: The electron will come back to the original state either in one jump or more jumps.
