AP CHEM SUMMARY 29 Sept. 2011 AP CHEMISTRY: UNIT 2 [pgs. 198-273, chapters 6-7] Scientific Laws, Theories, and BIG Ideas The Wave Nature of Light Electromagnetic Radiation ? energy carried through space (ex/ light) Dual-nature of Electrons & Photons Quantized Energy: Planck?s Constant (see Equations section); only a certain fixed quanta of energy is emitted (one/ a few fixed wavelengths) Photoelectric Effect: light can be particle-like (photons) Electrons have energy and frequencies associated with them and require a certain quanta of energy to change energy levels. Electrons Energy is negative and becomes less negative as you go outward Writing electron configurations: n = size of path (Principle Quantum Number, a.k.a. P.E.L)
