Bohr Model of the Atom
Proposition 1: Nuclear Model is Correct The nuclear model is the only way to expain the gold foil experiments.
Part 3(e): Atomic Physics
Bohr Model of the Atom
Proposition 2: Atoms Exist The are
special
electron orbits in the atom which violate the known laws of physics and
do not cause the emission of e-m waves
(photons).
Part 3(e): Atomic Physics
Bohr Model of the Atom
Although a given electron has KE and PE and is jiggling, if it is in a special orbit (characterized by a precise amount of KE and PE), it does not give up its energy in the form of a photon.
Part 3(e): Atomic Physics
Bohr Model of the Atom
Proposition 3: Atom emits a photon only when the electron "jumps" from a higher energy orbit to a lower energy orbit.
Since the special orbits are characterized by a specific amount of total energy, only specific amounts of energy will be available to produce a photon.
Part 3(e): Atomic Physics
Bohr Model of the Atom
Quantum Mechanics The electrons energy in the atom is not continuous, but that energy is realized in “bits.” The atom is said to be
quantized
. The area which studies these bits of energy is called
quantum mechanics
.
