CHE K121 Lecture Notes - Lecture 17: Atomic Number, Magnetic Quantum Number, Lanthanide
Document Summary
Quantum numbers: solving the wave equation gives a set of wave functions, or orbitals, and their corresponding energies, each orbital describes a spatial distribution of electron density, an orbital is described by a set of three quantum numbers. P orbitals: the value of l for p orbitals is 1, they have two lobes with a node between them. Energies of orbitals (hydrogen: one - electron hydrogen atom, orbitals on the same energy level have the same energy. "4: the spin of an electron describes its magnetic eld, which a ects its energy. Monday, october 29, 2018: this led to the spin quantum number, " ms, the spin quantum number has only two allowed values, " 4p5: orbital diagrams, each box in the diagram represents one orbital, half-arrows represent the electrons, the direction of the arrow represents the relative spin of the electron.
