Topological indices are important tools to modeling chemical properties of molecules. ve-degree based atom-bond connectivity, sum-connectivity, geometric-arithmetic, and harmonic indices are defined as their corresponding classical degree based counterparts recently in chemical graph theory. In this study we investigate ve-degree atom-bond connectivity, sum-connectivity, geometric-arithmetic, and harmonic topological properties of copper oxide.We calculate exact values of these novel topological indices for copper oxide and give closed formulas.
