WARM UP 1.List the 3 particles found in atoms. 2.Which of the 3 particles (from #1) are in the “cloud?” 3.What are the particles (from #2) doing in the cloud?

The Electron Cloud

Waves Transmit energy

Waves Electromagnetic spectrum –Continuous gradient (radio to gamma)

Particles Transmit energy Distinct values

Electron Cloud Werner Heisenberg –Electrons move randomly

Wave / Particle Duality Albert Einstein –Photoelectric effect Light waves release metal e - Light is both a wave and a particle

Wave / Particle Duality Louis de Broglie –e - behave like both particles and waves

Electron Cloud Heisenberg Uncertainty Principle –You can’t use the wave and particle at the same time

Bohr Model Max Planck –Emission spectra –Levels of energy in e -

Bohr Model Niels Bohr –Orbital model e - in rings

Bohr Model Light released when e - drop from a higher shell to a lower one

WRAP UP 1.Do you like the Bohr model or the electron cloud model better? Why?
