ΔE=-RE (1/n2f - 1/n2i )
Solution
It seems like you didn't provide a question. The formula you've given is for calculating the change in energy (ΔE) in a hydrogen atom when an electron transitions between energy levels. The formula is:
ΔE = -RE (1/nf² - 1/ni²)
Where:
- ΔE is the change in energy
- RE is the Rydberg constant for hydrogen (approximately 2.18 x 10^-18 joules)
- nf is the final energy level
- ni is the initial energy level
Please provide a specific question related to this formula for further assistance.
