单词	effective nuclear charge
释义	effective nuclear charge 简明释义有效核电荷：在多电子原子中，某一个电子所受的净正电荷。这个概念是基于屏蔽效应理论而存在：由于共同带有负电荷的内外层电子之间存在排斥力，内层电子“阻挡”了一部分外层电子与原子核之间的正负电荷吸引力。应用这个概念，可以直接根据原子的氧化值判断核电荷的强度。网络释义 1 ?有效核电数荷 ... 电离能(Ionization Energy) 电子亲和势(Electron Affinity) 电负性（Electronegativity）有效核电数荷（effective nuclear charge）化学键(chemical bond) ... 短语 1 effective nuclear charge number 有效核电荷数 2 effective fractional nuclear charge number 有效分数核电荷数双语例句 1 Because of its lower effective nuclear charge, xenon is more easily oxidized than krypton. 因为氙的有效荷电荷较低，所以氙比氪容易被氧化。 2 The first ionization potentials of the noble gases provide a measure of how firmly the outer electrons are held by the effective nuclear charge. 稀有气体的一阶电离势提供了一个评价的标准，能衡量外层电子被有效核电荷束缚的强度。
