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
铀:银白色的重金属元素,有放射性并且有毒,容易被氧化。已知有14个同位素,其中U238是自然界含量最多的。这种元素存在如沥青铀矿和钒钾铀矿等几种矿中,并从中提炼和加工,主要用于研究,核燃料和核武器。原子序数为92;原子量为238.03;熔点为1,132=C;沸点3,818=C;比重18.95;化合价2,3,4,5,6参见 element

注释
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.
元素铀的发现对现今的核子时代是至关重要的。它的名称是据在它之前发现的天王星命名的。威廉·赫歇尔爵士于1781年发现了天王星,并起名为Georgium sidus, “乔治的行星”, 用来纪念乔治三世。有人称之为赫歇尔, 但传统的力量更巨大,最终这颗行星被称之为Uranus (现代拉丁文和英语形式),如用其余的行星一样是用天神的名字命名的。在拉丁神话中被称作优拉纳斯神,而在希腊神话中被作优拉诺斯神,之所以选中这个天神因为他是萨图恩(希腊神话中为克洛诺斯)的父亲,而萨图恩是和他临近的行星;他还是朱庇特(希腊神话中的宙斯)的父亲,而宙斯又是下一颗临近的行星。这颗新行星的名字又用来命名一种新发现的化学元素,铀 是由M.H.克拉普罗特八年后发现的。 克拉普罗特这位德国科学家给予它铀 这种拉丁字母是为了纪念 天王星的发现。 Uranium在这之后不久进入英语, 首次出现于1797年出版的大不列颠百科全书 的第三版中
