Electron Configurat
Chapter 4 Electron Configuration
| Question | Answer |
|---|---|
| How do we study electron behavior? | -By researching electricity and particularly by analyzing light emitted and absorbed by substances |
| Define Light | -Electromagnetic radiation (form of radiant energy) |
| How does light travel through space? | -Wave-Partial Duality which is light exhibiting properties of both wave and particle |
| Wavelength Behavior | -Where light is a beam of energy traveling through space like an ocean wave |
| Particle Behavior | -Where light interacts with atoms and molecules as if it were a stream of tiny fast moving particles (photons) |
| Wavelength Behavior | -Electromagnetic waves consist on electric and magnetic fields oscillating at right angles to each other and in the direction of its motion |
| Four Wave Characteristics | -Amplitude -Wavelength -Speed -Frequency |
| Amplitude | -the height or depth of the wave measure from origin to peak or trough |
| Wavelength | -The distance that a wave travels as it completes one full cycle |
| Frequency | -The measure of the number or times a light wave completes a cycle in one second -Visible range 4E14 to7E14 S-1 |
| Speed | -Of light regardless of type of radiation moves through a vacuum of space at a constant rate |
| What kind of relationship do wavelength and frequency have? | -Inverse -when there is a high frequency there is a short wavelength and with a low frequency there is a long wavelength |
| Quantum Theory | -Scientists wondered why a different range of wavelengths are emitted at different temps |
| What is the Electromagnetic Spectrum in order? | -Radio-waves, Microwaves, IR, Visible, UV, X-Rays, Gamma, Cosmic |
| What is Planck's theory? | -That the energy absorbed or emitted by atoms is quantized |
| Photo-electric effect | -Property of metals to emit light when exposed to radiation of sufficiently high frequency |
| Photons | -tiny particles -carries energy based on frequency |
| What makes up the atomic spectrum? | -Frequencies of light emitted or absorbed by an atom |
| What are the 5 energy levels? | 1. Lyman Series 2. Balmer Series 3. Paschen Series 4. Bracket Series 5. Pfund Series |
| Heisenberg Principle | -It is impossible to know exactly the momentum and position of an electron at the same time because light used to observe causes excitation so electron moves once location is determined |
