| Question |
Answer |
| Electromagnetic radiation |
A form of energy exhibiting wavelike behavior as it travels through space. |
| Wavelength |
The shortest distance between equivalent points on a continous wave; is usually expressed in meters, centimeters, or nanometers. |
| Frequency |
The number of waves that pass a given point per second. |
| Amplitude |
The height of a wave from the origin to a crest, or from the origin to a trough. |
| Electromagnetic spectrum |
Includes all forms of electromagnetic radiation, with the only differences in the types of radiation being their frequencies and wavelengths. |
| Quantum |
The minimum amount of energy that can be gained or lost by an atom. |
| Planck's constant |
h, which has a value of `6.626x10^-34 (J=Joule) |
| Photoelectric effect |
A phenomenon in which photoelectrons are emitted from a metal's surface when light of a certain frequency shines on the surface. |
| Photon |
A particle of electromagnetic radiation with no mass that carries a quantum of energy. |
| Atomic emission spectrum |
Set of automatically emitted frequencies from the electromagnetic waves. |
| Ground state |
An atoms lowest allowable energy state. |
| De Broglie equation |
Predicts that all moving particles have wave characteristics and relates each particle's wavelength to its freqency, its mass, and Planck's constant. |
| Heisenberg uncertainty principle |
States that it is not possible to know precisely both the velocity and the position of a particle at the same time. |
| Quantum mechanical model of the atom |
Eectrons are treated as waves. |
| Atomic orbital |
Describle the electrons propable locations. |
| Principal quatum numbers |
Indicate the relative sizes and energies of orbitals. |
| Principal energy levels |
An atoms major energy levels. |
| Energy sublevels |
The energy levels contained within a principal energy level |
