Question | Answer |
electromagnetic radiation | a form of energy exhitbiting wavelike behavior as it travels through space. |
wavelength | the shortest distance betweeen equivalent points on a continuous wave; |
frequency | the number of waves that pass a given point per second |
amplitude | the height of a wave from the origin to a crest, or from the origin to a trough. |
electromagnetic spectrum | all forms of electromagnetic radiation, with the only differences in the type of radiation being their frequences and wavelengths. |
quantum | the minimum amount of energy that can be gained or lost by an atom |
Planck's constant | is the symbol for joules the SI unit of energy |
photoelectric effect | surface when light of a certain frequency shines on the surface |
photon | a particle of electromagnetic radiation with no mass that carries a quantum of energy |
atomic emission spectrum | the set of frequencies of the electromagnetic waves emitted by atoms of the element |
ground state | lowest allowable energy state of an atom |
de Broglie equation | predicts that all moving particles have wave characteristics |
Heisenberg uncertainty principle | states that it is not possible to know precisely both the velocity and the position of a particle at the same time |
quntum mechanical model of the atom | an atomic model in which electrons are treated as waves; also called the wave mechanical model of the atom |
atomic orbital | a three-dimensional region around the nucleus of an atom that describes an electron's probable location |
principal quantum number | which the quantum mechanical model assigns to indicate the relative sizes and energies of atomic orbitals. |
principal energy level | the major energy levels of an atom |
energy sublevel | the energy levels contained within a principal energy level |
