WebChemistry questions and answers. The electronic configuration of nitrogen (Z 7) is 1s22s22p3. There is an empirical rule (i.e. Hund's rule) that requires the electrons in unfilled shells to have quantum numbers so that the sum of the z components of their spins has the maximum possible value. Using this rule, give the complete set of quantum ... WebJan 30, 2024 · Hund's rule states that: Every orbital in a sublevel is singly occupied before any orbital is doubly occupied.

In atomic physics, Hund's rules refers to a set of rules that German physicist Friedrich Hund formulated around 1927, which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom. The first rule is especially important in chemistry, where it is often referred to simply as Hund's Rule. The three rules are:
