What is Hund’s rule for filling electron orbital diagrams?

Hund’s rule states that orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron and that each of the single electrons must have the same spin. The Figure below shows how a set of three p orbitals is filled with one, two, three, and four electrons.

What is Klechkowski rule?

Klechkowski First Rule or n + l rule: According to this rule, the electron enters the subshell first, for which the value of n + l is low. For example n = 1 and l = 0 for 1s subshell. And n = 2 and l = 0 for 2s subshell. So that n + l = 1 for 1s and n + l = 2 for 2s subshell.

What do SPDF stand for?

The spdf stands for sharp, principal, diffuse, and fundamental respectively. These letters are used as the visual impression to describe the fine structure of the spectral lines that occurs due to the spin orbital interaction.

What is Paulis rule?

Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).
