Construction of neighbourly irregular chemical graphs among s-block and p - block elements combinationsand its size

A connected graph G is said to be neighbourly irregular, if no two adjacent vertices of G have the same degree. Given a positive integer n and a partition n with distinct parts. In this paper, we could derive some Neighbourly Irregular Chemical Graph (NICG) of molecular structure which is derived from the s-block elements and p-block elements combinations in the area of Inorganic Chemistry. Considering the atom as vertices, covalent bond as edges, and valence as degree of vertices. Also I have derived the size of such Neighbourly Irregular Chemical Graph (NICG).
