What Does EAN Stand For?

EAN stands for Effective Atomic Number

Effective Atomic Number (EAN) is a concept used in chemistry to describe the effective positive charge experienced by electrons in a given atom, particularly in the context of complex formation and bonding. It accounts for the number of valence electrons surrounding a central atom, adjusted for factors such as coordination and electron donation from ligands. The EAN helps predict the stability and reactivity of coordination compounds and plays a critical role in the analysis of metal-ligand interactions.
