Answer :
When an electron transitions between energy levels in a hydrogen atom, energy is either absorbed or released. Here's what happens in this specific scenario:
1. Understanding the Transition:
- The electron starts at a higher energy level, [tex]\( n=2 \)[/tex], and moves to a lower energy level, [tex]\( n=1 \)[/tex].
2. Energy Transition:
- When an electron moves from a higher energy level to a lower energy level, it releases energy.
- The difference in energy between these two levels is given as [tex]\( 1.64 \times 10^{-18} \)[/tex] joules.
3. Result of the Transition:
- Since energy is released during the transition from [tex]\( n=2 \)[/tex] to [tex]\( n=1 \)[/tex], the amount of energy released is exactly equal to the difference between these energy levels.
- Therefore, exactly [tex]\( 1.64 \times 10^{-18} \)[/tex] joules of energy is released.
4. Correct Option:
- Based on the information above, the correct answer is:
- b) Exactly [tex]\( 1.64 \times 10^{-18} \)[/tex] J of energy is released.
This provides a clear explanation of what occurs during the energy level transition and why option b is the correct choice.
