TermDefinition
Electromagnetic radiation a form of energy that exhibits wavelike behavior as it travels through space
Electromagnetic Spectrum Formed by all the forms of electromagnetic radiation
Wavelength the distance between corresponding points in adjacent waves
Frequency number of waves that pass through a specific point time
Hertz the measure of frequency waves/second
Ground State The lowest energy state of an atom
Excited State A state in which an atom has a higher potential energy than its qround state
Line Spectrum The spectrum of 4 colors emitted through a prism
Continuous Spectrum The spectrum of a continuous range of frequencies of electromagnetic radiation
Emission When the electron falls to a lower energy level a proton is emitted
Absorbtion Energy must be added to an atom in order to move an electron from a lower energy level to a higher energy level
Orbital A three-dimensional region around around the nucleus that indicates the probable location of an electron
Principal quantum number "n" indicates the main energy occupied by an electron occupied by the electron
Angular momentum quantum number Symbolized by "l" indicates the shape of the orbital
Electron configuration The arrangement of electrons in an atom
Noble Gas Group 18 elements (helium, neon, argon, krypton
Noble Gas Configuration An outer main energy occupied in most cases by 8 electrons
