spectroscopy & bohr model

what is the problem with Bohr’s model

it only works for hydrogen

what was the problem with rutheford’s model

it didnt explain atomic absorption and emission spectra & it was not sustainable

bohr model

electrons are moving in orbits, and those orbits have definite energies, and the energies of electrons in atoms are quantized

on energy diagrams what transition of energy would produce an absorption spectrum

lower energy to higher energy (absorbing energy)

what types of colors do higher energy match

darker colors=higher energy levels

how are absorption and emission different from the photoelectric effect

• photo electric effect:atom absorbs a proton resulting in ejection of an electron & the electron completely leaves the atom

  • ionization

what should the atom model include

electrons in atom can only have certain energies since they are quantized, we can’t know the exact position of the electron since we know its energy
