Abstract

We propose a more general wording for Madelung rule using a new descriptor based on the four quantum numbers n, ℓ, m_ℓ, m_s of the most recently added electron notes K(_ZX). By this formulation, K(_ZX) will increment as the atomic number Z increases. No exceptions will remain. It can be connected to the first ionization energy.

Keywords

Pauli principle, Madelung-Klechkowski and Hund rules, aufbau principle
