Sommerfeld Atom Model

According to Sommerfeld, the path of an electron around the nucleus, in general, is an ellipse with the nucleus at one of its foci. In order to explain the observed fine structure of spectral lines, Sommerfeld introduced two main modifications in Bohr’s theory. According to Sommerfeld’s model, for any principal quantum number n, there are n possible orbits of varying eccentricities called sub-orbits or sub-shells. In this way, the attempt of Sommerfeld to explain the fine structure of spectral lines failed. But soon, on the basis of variation of mass of electron with velocity, Sommerfeld could find the solution for the problem of the fine structure of the spectral lines.

great work sister

[@kandasamymatricschoolkmhss6067]

NICE VIDEO

[@soumyadipbanerjee6744]

you are wrong with the concept of the azimuthal quantum number.The azimuthal quantum number in the Bohr-Sommerfeld theory is not similar to the azimuthal quantum number introduced by quantum mechanics.In Bohr Sommerfeld theory k=1when n=1; k=1,2when n=2and so on,here k is the azimuthal quantum number which can have more than one value for a specific subshell .Better get your concept correct

[@mohitpanwar1126]

But can't we just take azimuthal no.as they are (not Sommerfeld's) ...and just replace l in the formula with l+1 ..just like she did.. Isn't it all the Same
