Actinide chemistry (or actinoid chemistry) is one of the main branches of nuclear chemistry that investigates the processes and molecular systems of the actinides. The actinides derive their name from the group 3 element actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide. All but one of the actinides are f-block elements, corresponding to the filling of the 5f electron shell; lawrencium, a d-block element, is also generally considered an actinide. In comparison with the lanthanides, also mostly f-block elements, the actinides show much more variable valence. The actinide series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.

  • 錒系化學(Actinide chemistry)是核化学中的一個主要分支領域,研究錒系元素的反應以及其分子系統。錒系元素的名稱得名自3族元素錒Ac。而錒系元素常會用An來表示。錒系元素中絕大多數都是f區元素,最高能量的電子是在5f電子層,其中只有鐒例外,鐒是d區元素,不過多半仍算在錒系元素中。相較於也在f區的鑭系元素,錒系元素的價態變化較多。錒系元素中有15個金屬元素,其原子序從89至103,分別對應從錒到鐒的化學元素。 (zh)
