CHEM 1320 Lecture Notes - Lecture 22: Radio Wave, Photon
Document Summary
1. quantum mechanics forms the foundation of chemistry: explains the periodic table b) c) the behavior of the elements in chemical bonding provides the practical basis for lasers, computers, and countless other applications. 1. electrons are incredibly small: a single speck of dust has more electrons that the number of people who have ever lived on earth. 1. quantum-mechanical model: explains the manner in which electrons exist and behave in atoms a) it helps us understand and predict the properties of atoms that are directly related to the behavior of the electrons. The nature of light: its wave nature: de nition. 2. light: a form of electromagnetic (em) radiation two perpendicular waves: electric eld: region where an electrically charged particles experience a force, magnetic eld: region where a magnetized particle experiences a force. 3. all em waves move at the same speed: 3. 00 x 10^8 m/s = the speed of light (c)
