|---|---|---|---|---|---|
| Absorption Spectrum | shows the pattern of electromagnetic radiation lines absorbed by atoms of an element which are at their ground state energy level; each element has its own unique absorption spectrum.
🗑
|
||||
| Emission Spectrum | shows the pattern of electromagnetic radiation lines emitted by atoms of element which have been at an excited state energy level; each element has its own unique emission spectrum.
🗑
|
||||
| Electromagnetic Radiation | transverse waves that are emitted from electrically charged particles.
🗑
|
||||
| Electromagnetic Spectrum | complete range of wavelengths which light can have. These include radio, infrared, visible, ultraviolet, x
🗑
|
||||
| Electron Cloud Model | current model of the atom that describes the allowed energies an electron can have and the most probably locations of electrons around the nucleus.
🗑
|
||||
| Energy Level | each electron’s fixed amount of energy.
🗑
|
||||
| Quantum (of energy) | the amount of energy to move an electron from its present energy level to the next higher one.
🗑
|
||||
| Excited State | an increased energy level of an electron; this is achieved by absorbing a quantum of energy.
🗑
|
||||
| Ground State | the lowest possible energy of an electron.
🗑
|
||||
| Wavelength | the distance between a point on one wave and the identical point on the next wave.
🗑
|
||||
| Frequency | the number of wavelengths that pass one place each second.
🗑
|
||||
| Orbital | one part of a sublevel; each orbital can hold two electrons.
🗑
|
||||
| Valence Electron | electrons in the outermost energy level of an atom.
🗑
|
||||
| Electron Configuration | a representation of the number of electrons of an atom or ion and the orbitals in which they lie.
🗑
|
||||
| Sublevel | one part of an energy level, each sublevel can hold different numbers of electrons.
🗑
|
||||
| Heisenberg Uncertainty Principle | it is impossible to know exactly both the velocity and the position of a particle at the same time
🗑
