Conversely, the variation of active metals does not follow the trend well and show poor correlation, which impacts the overall BEP trend. The strong correlation observed within the spectator atom variation can be attributed to the systematic nature of the change of the spectator atom. The active metal stays the same, and the binding modes and orbitals do not alter, suggesting electronic communication between the second-shell coordinated spectator atoms and the active metal. Thus, BEP relationship does not uniformly apply well to all cases. Still, it holds better when examining the influence of spectator atoms. However, changes in active metals do not align as closely with the predicted BEP relationship.
