Using the undirected network from our previous paper, we constructed 5 directed networks based on 5 electronegativity scales. The direction of the edges is determined by the differences in electronegativity. We found that indegree and outdegree can be viewed as inherent chemical properties of elements. Thus, we define a new index-comparative attractiveness (CA)-to study the relationship between this index and electronegativity. The results indicate that CA and electronegativityis are correlated and highly consistent, and can be regarded as an internal property of elements. This index can be used to predict potential binary compounds and assess the rationality of electronegativity, providing valuable insights into the study of electronegativity and a new perspective on chemical properties.
