CHEM 1211 Lecture Notes - Lecture 2: Niels Bohr, Electromagnetic Spectrum, Bohr Model
Document Summary
Chem 1211 chapter 2: **electromagnetic spectrum**: electromagnetic radiation includes a range of energies, from radio waves to gamma rays. Visible light is a small portion of the electromagnetic spectrum, and different colors correspond to different energies: **quantization of energy**: energy is quantized, meaning it can only exist in discrete amounts. The energy levels are quantized, and electrons can only occupy these discrete levels: **quantum mechanics**: quantum mechanics provides a more accurate description of atomic structure and electron behavior than the bohr model. The wave-particle duality of electrons is taken into account, and electron orbitals are described as probability distributions rather than fixed orbits: **orbitals and electron configuration**: orbitals are regions in space where electrons are likely to be found. They come in different shapes (s, p, d, f) and have specific energy levels. Covalent bonding involves the sharing of electrons between atoms.
