Usage
Confusion can arise over whether to write used to or use to, largely because the pronunciation is the same in both cases. Except in negatives and questions, the correct form is used to: we used to go to the cinema all the time. However, in negatives and questions using the auxiliary verb do, the correct form is use to, because the form of the verb required is the infinitive: I didn't use to like mushrooms.
Etymology
ME: the noun from OFr. us, from L. usus, from uti ‘to use’; the verb from OFr. user, based on L. uti.

對答案
目前的元素週期表中有七個週期，並以118號元素鿫（Og）終結。如果有更高原子序數的元素被發現，則它將會被置於第八週期、甚至第九週期。這些額外的週期預期將會比第七週期容納更多的元素，因為經過計算新的g區將會出現，第八及第九週期將在32個元素的基礎上額外包含18個g區元素，各週期中均存在部分填滿的g原子軌域。這種擁有八個週期的元素表最初由格倫·西奧多·西博格於1969年提出。
第八或以上週期的元素未曾被合成或於自然發現。（2008年4月，Amnon Marinov宣稱在自然界中發現122號元素Ubb，但該報告被廣泛認為是錯誤的。）g區內第一個元素的原子序數應該為121，根據IUPAC元素系統命名法命名為Unbiunium，符號Ubu。此區域內的元素很可能具有放射性，並且高度不穩定，半衰期極短。然而穩定島理論預測位於126號元素Ubh附近的元素將處於穩定島內，不會有自發分裂，但會發生α衰變，且這些元素的部分同位素可能具有相對極長的半衰期。而穩定島之後還能存在多少物理上可能的元素至今仍沒有定論。
根據量子力學對於原子結構解釋的軌域近似法，g區會對應不完全填滿的g軌域。不過，自旋-軌道作用會削弱軌域近似法所得結果的正確性，這可能會發生在較大原子序的元素上。
