Hello, I was trying to solve a problem in my course book, and I noticed I don't really understand energy levels completely. My ignorance covers more than one specific problem, so I figured I'd ask a general question, rather than post the problem.

The Rydberg formula: ## \frac{hc}{λ}=hcR(\frac{1}{n_L^2}-\frac{1}{n_U^2}) ##.
Total energies in Bohr model: ## E_n=-\frac{hcR}{n^2} ##.

Making the statement "energy required to ionize a specific atom is ## E_i ##," doesn't that mean "energy difference between levels ## n \rightarrow \infty ## and ##n=1## is ##E_i##?"

Thanks in advance!

Not quite: an atom can be ionised from any initial energy level, not just n = 1. Other than that, your reasoning is correct.
