WGU c832 Chemistry with Lab. Questions and answers, 100% Accurate, VERIFIED. principal quantum number (n) - -symbolized by n, indicates the main energy level occupied by the electron. positive integers (1,2,3...) shell - -set of orbitals with the same principal quantum number, n. atomic orbital - -a region of space in which there is a high probability of finding an electron. mathematical function that describes the behavior of an electron in an atom, wave function. angular momentum quantum number (l) - -the quantum number that indicates the shape of an orbital. (0,1,2...n-1) subshell - -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. s orbitals are what shape? - -spherical region of space with high electron density, describes orbitals with l=0. An electron in this orbital is called an s electron. p orbital shape - -peanut or dumbbell shaped region of space with high electron density, describes orbitals with l =1. d orbital shape - -4 leaf clover. l=2 magnetic quantum number (ml) - -the quantum number that indicates the orientation of an orbital around the nucleus; orbitals having different values of ml but the same subshell value of l have the same energy (are degenerate), but this degeneracy can be removed by application of an external magnetic field. (l, l-1,...,-l) spin quantum number - -has only two possible values (+1/2, -1/2) which indicate the two fundamental spin states of an electron in an orbital. ms. Pauli Exclusion Principle - -no two electrons in the same atom can have the same set of four quantum numbers. degenerate orbitals - -orbitals that have the same energy electron density - -a measure of the probability of locating an electron in a particular region of space, it is equal to the squared absolute value of the wave function.
