Some physical and chemical qualities, that critical mass and durability of chemical substances, correlated with topological indices. It is common to link topological indices with QSPR and QSAR, which stand for quantitative structure activity relationships, when discussing their importance. The ability to traverse edges in just one direction characterizes directed graphs. An internal graph structure known as a rooted tree for any set G where the nodes are vertices, a normal tree is one in which the tree-order of the nodes' ends is similar. One of the most valuable nanomaterials in many fields, A human hair is one millionth of its thickness. the neighborhood zeroth order index (NZ(ſ)), and the fifth geometric-arithmetic index (GA5).
