Chapter 6: Electronic Structure and Periodic Properties of Elements Vocabulary

number specifying the electron spin direction, either +1/2 or -1/2

localized wave phenomenon characterized by discrete wavelengths determined by the boundary conditions used to generate the waves; standing waves are inherently quantized

atomic orbitals with the same values of n and l

electrons in the high energy outer shell(s) of an atom

high energy outer shell(s) of an atom

oscillation of a property over time or space; can transport energy from one point to another

observation that elementary particles can exhibit both wave-like and particle-like properties

mathematical description of an atomic orbital that describes the shape of the orbital; it can be used to calculate the probability of finding the electron at any given location in the orbital, as well as dynamical variables such as the energy and the angular momentum

distance between two consecutive peaks or troughs in a wave
