Unit 2 AtomicStruct
| Term | Definition |
|---|---|
| Atomic emission spectrum | The variety of frequencies of electromagnetic radiation (light) seen through a spectroscope that are emitted by electrons as they transition from higher to lower energy levels; unique for each element. |
| Atomic radius | One-half of the distance between the center of identical atoms that are not bonded together. |
| electromagnetic spectrum | All of the frequencies or wavelengths of electromagnetic radiation |
| electronegativity | A measure of the ability of an atom in a chemical compound to attract electrons |
| frequency | the number of cycles or vibrations per unit of time also the number of waves produced in a given amount of time |
| Hyphen notation | A way of designing the isotopes of an element using its name (or symbol), a hyphen, and the mass number . |
| 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 an atom or ion |
| isotope | an atom that has the same number of protons as other atoms of the same element but that has a different of neutrons |
| planck's 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 outer most shell of an atom and that determines the atoms chemical properties |
| wavelength | the distance from any point on a wave to an identical point on the next wave |
