Abstract Electronegativity ( χ ) is an important physico-chemical concept to study the chemical structure and reactivity. Although, the conundrum related to measurement of electronegativity still persists. In view of this fact, a simple yet rigorous scale of electronegativity ( χ ), invoking an inverse relationship with atomic nucleophilicity index ( N ), has been proposed for 103 elements of the periodic table. The computed data follows periodicity distinctly satisfying all the sine qua non of a standard scale of electronegativity. Further, electronegativity values display a sound similarity with the standard electronegativity scales validating the suitability of the proposed model. Molecular electronegativities of some polyatomic molecules have also been calculated using the proposed scale of electronegativity. Graphic Abstract

以原子亲核指数表示的原子电负性标度

摘要 电负性（ χ ）是研究化学结构和反应性的重要物理化学概念。尽管如此，与电负性测量相关的难题仍然存在。鉴于这一事实，已经为元素周期表的 103 种元素提出了一个简单而严格的电负性 (χ) 标度，该标度与原子亲核性指数 (N) 呈反比关系。计算出的数据遵循明显满足标准电负性标度的所有必要条件的周期性。此外，电负性值显示出与标准电负性量表的相似性，验证了所提出模型的适用性。一些多原子分子的分子电负性也已使用建议的电负性标度进行计算。图形摘要
