### Are these equations only specific to H-atoms?

So, from what I understand, the Bohr Frequency Condition and equation for calculating energy of different n levels are specific to H atoms.
Professor Lavelle mentioned C-atom during the lecture and I was wondering if we know the condition for C-atoms?
Just to make sure, are these condition and equation specific to H atoms only? and if so, does every element have different conditions?

I'm a little confused on the atomic spectra section. Thanks for helping me out!

Yes, the Bohr Frequency Condition and the equations for energy are specific only for Hydrogen only because Hydrogen only has one electron. If we use another element that has multiple electrons, then technically those electrons would be repelling each other, so the Bohr Frequency Condition would not apply to this situation.

For the bohr frequency condition, the equation contains Rydberg's constant (3.29x10^15 Hz); and that constant only works on hydrogen atoms or hydrogen-like atoms such as He+.
