Atomic emission spectrum | The variety of frequencies of electromagnetic radiation (light) seen spectroscope that are emitted by electrons as they transition from higher to lower energy;unique for each element. |
Atomic radius | one half 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 compund to attract electrons |
frequency | the number of cycles or vibration per unit |
hyphen notation | A way of designing the isotopes of an element using it name |
ionic radius | the 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(or the same atomic number)as other atoms of the same element but has different number of neutrons |
planks constant | a constant value that relates the energy of a photon of light to its frequency |
valence electrons | an electrons that is found in the outermost shell of an atom and that determines the atoms chemical properties |
wavelength | the distance from any point on a wave. |
