Models of the Atom - Orbits to Clouds
Bohr:1. Newton’s 2nd Law… electric force
causes electron to move at velocity
v at radius r. k e2/r2 = m v2/r
2. Energy is kinetic and electric.
E = 1/2 m v2 - k e2/r
3. Angular motion is “quantized”.
L = m v r = n h/ 2 p
4. Photon equals energy difference
Ef - Ei = h f
