Atomic Structure
Term | Definition |
---|---|
Atomic Emission Spectrum | The variety of frequencies of electromagnetic radiation (light) seen through a spectroscope |
Atomic Radius | One-half of the distance between the center of identical atoms that are not bonded together. |
Electromagnetic Radiation | The radiation associated with an electric and magnetic field; it varies periodically and travels at the speed of light. |
Electronegativity | A measure of the ability of a atom in a chemical compound to attract electrons. |
Frequency | The number of cycles or vibrations per unit of time also number of waves produced in a given amount of time |
Hyphen notation | A way designing the isotopes of an element using its name for symbol), a hyphen, and the mass number (example: uranium-238 |
Ionic Radius | A measure of the size of an ion of an element in a crystal |
Ionization Energy | The energy required to remove an electron from atom or ion |
Isotope | An atom that has the same number of protons in another atoms of the same element but has different neutrons |
Plancks Constant | A constant value that relates the energy of a photon of light to its frequency |
Valence Electron | An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties |
Wave Length | the distance from any point on a wave to an identical point on the next wave |
