Bohr model

1. e- orbit + nucleus in 1/r^2 potential like planets.

a. circular orbits

b. does not radiate or decay

2. Electrons jump between orbits with photons E=hf

a. jump to closer orbit emit photon

b. jump to distant orbit absorb photon

(jump = disappear and rematterialize)

3. Orbits are restricted to l =nh/2p n = 1,2,3.....

(l is angular momentum = speed*mass * radius)

Summary of laws

Hydrogen lines

Explanation

HSC : 1/wavelength =R (1/n1^2-1/n2^2)

E(eV) = 13.6(1/n1^2- 1/n2^2)

wavelength = 91.15

(1/n1^2-1/n2^2)

= 91.15xn1^2xn2^2 / (n2^2-n1^2)
