【 摘 要 】

Hund's maximum multiplicity rule as stated in most elementary and intermediate level textbooks on general and inorganic chemistry and usually taught at the college and undergraduate level is incorrect. It is true that electrons entering a subshell of an atom tend to occupy the orbitals singly as far as possible but not necessarily with parallel spins. Also, proper definitions and correct use of terms like configuration, microstate, spectroscopic term, level and state are essential if confusion on the part of the student, especially the beginner, is to be avoided.
