※ 引述《ymmars (闭关中....)》之铭言：
: 另外 金兰系收缩又是在说些什麽内容呢？
之前查paper时的资料...参考一下吧!!
Lanthanide contraction is a phenomenon where the atomic radii of elements in
the lanthanide series (Z=58 to 71) are smaller than would normally be expected.
Since electrons in an f subshell poorly screen electrons from the nucleus, the
outer-shell electrons are held more tightly; this results in a smaller atomic
radii.
镧系收缩应该只的是原子半径跟一边元素周期所预测的不尽相同...
跟轨域的壳层分部有关...详见上英文内容...英文不好不敢擅自翻译 XD
