※ 引述《ymmars (閉關中....)》之銘言：
: 另外 金蘭系收縮又是在說些什麼內容呢？
之前查paper時的資料...參考一下吧!!
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.
鑭系收縮應該只的是原子半徑跟一邊元素週期所預測的不盡相同...
跟軌域的殼層分部有關...詳見上英文內容...英文不好不敢擅自翻譯 XD
