Explain the success of Bohr's theory for hydrogen atom.

Explanation

Succes of Bohr.s Theory for hydrogen atom:
Bohr.s theory gave the information about the principal quantum number, Principal quantum number represents the stationary states, (n = 1, 2, 3, ....... integral numbers).
Bohr.s theory gave the information about the radius of the stationary states (or) orbits.
`r=0.529xxn^(2)Å` (or)
`r=52.9xxn^(2)" pm"`
`[r=(n^(2)h^(2))/(4pi^(2)m.e^(2))]` (for hydrogenation)
This theory gave the information about the energy of the electron of particular stationary state.
`E_(n)=-R_(H)[(1)/(n^(2))]n=1,2,3,.........`
`R_(H)=Ryd` berg constant
`=1,09,677cm^(-1)`
This theory explained the line spectra of hydrogenation.
This theory can also be applicable to the ions containing only one electron. `Eg:He^(+),Li^(+2),Be^(+3)`..
This theory can also gave information about velocity of electrons. moving in the orbits.
