Bohr incorporates Plancks's quantum theory into his model, placing conditions on the value of the angular momentum.
angular momentum = nh/2pi
n=principal quantum number h= Planck's constant
since its giving me the angular momentum, is it actually giving me a number that corresponds to an orbital. s,p,d, or f?
Bohr then equated the allowed values of the angular momentum to the energy of the e-. He obtained the folowing equation:
E=-R(little h)/n^2
R(little h) is Rydeberg constant for hydrogen right. N= principal quantum #
the value of zero was assigned to the state at which the e- and proton were separated completely. this makes sense since the bigger the n value is= the further orbit it is away from the proton= the closer the E gets to zero.
now i do not quite understand two things. Why the negative sign?? and E denotes the energy of the e- right. what exactly does this energy do or mean for the electron?
using this formula E=13.6-(13.6/n^2)
E = energy
n= energy level.
using that formula Bohr predicted the energy levels for each of the allowable orbits in the Hydrogen atom.
now i would like to understand why 13.6 is used?
and what does this information actually tell us.
please help as best you can. i have tried reading things up on Wikipedia but that does not help me much.
