Answer to Question #20160 in Atomic and Nuclear Physics for Dan
How can elements that have few electrons (like hydrogen)have so many sprectral lines? That is, how could hydrogen with only one atom produce so many lines.
Spectral lines are the results of electronic transitions between different energy levels. Every atom has it’s unique set of energy levels (there are a lot of them for every atom and they are discrete). Although hydrogen has only one electron, this electron (when atom is excited) can be located at any of energy levels mentioned above. This electron can transit to other energy levels (if certain conditions are followed and this transition is allowed according to transition rules), emitting or taking photons with energy |E_m-E_n | (E_m and E_n – energies of transition levels ). During experiments we observe this photons using specific devices and call them(photons) spectral lines. So elements that have few electrons (like hydrogen) have so many spectral lines because they have many energy levels and great number of possible electron transitions between them.
I just wanted to say thank you guys so much for helping me get through my statistics class. Any area in math has never been my strong field and thanks to you guys I was still able to pass my course.
thanks to you and all the people on your team that helped in me passing my course. :-)
