Electronegativity: An Insight in Terms of Atomic Number Approached Via Isoelectronic Series

Abstract

In this communication, an insight into electronegativity in terms of fundamental property, the atomic number (Z) is approached via isoelectronic series, using the electronegativity measure, (I+A)/2 (isoelectronic values) vs. atomic number plots. On the basis of these excellent smooth quadratic curves (r2≈1), we have inferred that the neutral atom electronegativity, (I+A)/2 is proportional to Z2. Our view justifies the suggestion made by Islam et al.
