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 |
