A network-based correlation research between element electronegativity and node importance

Abstract Abstracted from real compounds, chemical elements can be considered a system tied by bonds (or bonding relationships) between two elements, namely the element and bond system. Then, their properties studied view of complex networks. Based on previous work, we introduce polarity to judge edge direction select four electronegativity scales build directed Taking node importance as an example, discuss relationships chemistry Through quantitative analysis, scale changing trends in all networks are found follow similar periodic laws. And there exist statistically significant correlations most pairs. The further analysis proves meanings above scales. All these conclusions unassociated with specific scales, even if have different nodes edges, which prove rationality universality proposed method. Our research gives network explanation electronegativity, study more objects
