Document Summary
Chem 12 - lecture 14 - atomic models. Neil"s bohr, born in 1913, proposed the first modern model of the hydrogen atom. This model similar to how planets orbit the sunwith some form of centrifugal force. In that the centrifugal affect was made by the electrostatic attraction +/- btw the lectron & protons. And another problem came with the discovery of the wave properties of the electron. The oscillation associated with waves would yield orbitals that fluctuated in energy and imply that they are not quantized ie not possible. Bohr did develop an equation that explained the visible spectrum of lines for the hydrogen atom as the quantized absorption and emission of energy by atoms, when electrons shift from one energy level to another level. Where rh is the rydberg constant = 2. 18 x 10-18j, h = 6. 63 x 10-34j-s, v = frequency, ni is the initial state (where you start) and nf is the final state (where you end).
