n.Symbol U （名詞）符號 U
A heavy silvery-white metallic element, radioactive and toxic, easily oxidized, and having 14 known isotopes of which U 238 is the most abundant in nature. The element occurs in several minerals, including uraninite and carnotite, from which it is extracted and processed for use in research, nuclear fuels, and nuclear weapons. Atomic number 92; atomic weight 238.03; melting point 1,132=C; boiling point 3,818=C; specific gravity 18.95; valence 2, 3, 4, 5, 6.See table at element
鈾：銀白色的重金屬元素，有放射性並且有毒，容易被氧化。已知有14個同位素，其中U238是自然界含量最多的。這種元素存在如瀝青鈾礦和釩鉀鈾礦等幾種礦中，並從中提煉和加工，主要用於研究，核燃料和核武器。原子序數為92；原子量為238.03；熔點為1,132=C；沸點3,818=C；比重18.95；化合價2，3，4，5，6參見 element

註釋
The element uranium, whose discovery has been so vital to our nuclear age, owes its name to a preceding scientific discovery, that of the planet Uranus. Sir William Herschel, who discovered Uranus in 1781, named the planet Georgium sidus, 「the Georgian planet,」 in honor of George III. Some also called it Herschel, but convention prevailed and the planet came to be called Uranus (the form in Modern Latin and English), the name of a heavenly deity like the rest of the planets. Called Uranus in Latin mythology and Ouranos in Greek, this god of the heavens was chosen because he was the father of Saturn (Greek Cronos), the deity of the planet next in line, who was the father of Jupiter (Greek Zeus), the deity of the next planet. The name of this new planet was then used in the name of a new chemical element, uranium, discovered eight years later by M.H. Klaproth. Klaproth, a German scientist, gave it the Latin name uranium in honor of the discovery of Uranus. Uranium passed into English shortly thereafter, being first recorded in the third edition of the Encyclopedia Britannica, published in 1797.
元素鈾的發現對現今的核子時代是至關重要的。它的名稱是據在它之前發現的天王星命名的。威廉·赫歇爾爵士於1781年發現了天王星，並起名為Georgium sidus， 「喬治的行星」， 用來紀念喬治三世。有人稱之為赫歇爾， 但傳統的力量更巨大，最終這顆行星被稱之為Uranus （現代拉丁文和英語形式），如用其餘的行星一樣是用天神的名字命名的。在拉丁神話中被稱作優拉納斯神，而在希臘神話中被作優拉諾斯神，之所以選中這個天神因為他是薩圖恩（希臘神話中為克洛諾斯）的父親，而薩圖恩是和他臨近的行星；他還是朱庇特（希臘神話中的宙斯）的父親，而宙斯又是下一顆臨近的行星。這顆新行星的名字又用來命名一種新發現的化學元素，鈾 是由M.H.克拉普羅特八年後發現的。 克拉普羅特這位德國科學家給予它鈾 這種拉丁字母是為了紀念 天王星的發現。 Uranium在這之後不久進入英語， 首次出現於1797年出版的大不列顛百科全書 的第三版中
