镧系金属一系列物理化学性质在Eu和Yb处出现双峰(双谷)的现象称为“双峰效应”,并通常从两个方面进行解释:Eu和Yb是二价金属以及它们的金属半径大于其邻近的三价稀土.作者根据电子精细结构定量地计算了镧系金属的原子半径、密度、
A series of physicochemical properties of lanthanide metals The appearance of doublet (doublet) at Eu and Yb is called “bimodal effect” and is usually explained in two aspects: Eu and Yb are divalent metals and their metals The radius is greater than its adjacent trivalent rare earth.According to the electronic fine structure of the quantitative calculation of the lanthanide metal atomic radius, density,
