### En= -hR/n^2

So during lecture Professor Lavelle stated that this equation could only be used for Hydrogen atoms. Does this mean there are separate equations for other atoms that we will have to know or will we only be solving questions for H atoms for this class?

I think that there must be different equations because it shows on my notes that it works only for the H spectrum.

There is a way to modify this equation to make it work for one electron ions, however I believe we will only have to know the equation for Hydrogen atoms.

Yes, there are other equations for elements that contain more than one electron. But, this equation is not necessarily only for hydrogen, but for single electron atoms.

For example: Li2+, He+, Be3+, etc. also have one electron using the periodic table and their "z" value.
