effective nuclear charge

  • 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。

Effective nuclear charge

  • abstract: The effective nuclear charge (often symbolize as Z_{\mbox{eff}} or Z*) is the net positive charge experienced by an electron in a multi-electron atom. The term "effective" is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge by the repelling effect of inner-layer electrons.
