A Review Constants Periodic Table Learning Goal: To use electron configuration to explain magnetic behavior. Electron configuration The magnetic behavior of an atom or ion depends on its electron configuration. An important property that results from the electron configuration of an atom or an ion is behavior in the presence of an external magnetic field. Due to the random orientations...
