CHEM 130 Lecture Notes - Lecture 20: Magnetic Quantum Number, Atomic Orbital, Angular Momentum
Document Summary
Chem 130: general chemistry: macroscopic investigations and reaction principles - A wave function for an electron in an atom. Pictured qualitatively by describing the region of space where there is high probability of finding the electrons. A fourth quantum number (ms) shows the magnetic property of electrons, called spin. This quantum number is the one on which the energy of an electron in an atom principally depends. It can have any positive value: 1, 2, 3, . The smaller n is, the lower the energy. The size of an orbital also depends on n. The larger the value of n is, the larger the orbital. Orbitals of the same quantum state n belong to the same shell. Shells are designated by the following letters. Distinguishes orbitals of given n having different shapes. It can have any integer value from 0 to n-1.
