Group in the periodic table there are silver-white metallic luster of the solid metal transition element, atomic number Z = 26, atomic weight of 55847, chemical symbol Fe, there is a stable F isotope 5626Fe and a radioisotope 5526Fe, content of 5% of the earth's crust, accounting for elements of in the fourth place, the metal in the second melting point 1535 ℃, boiling point 2750 ℃, the relative density of 786, the external electronic structure 3d64s2, chemical reactions 2-6 tram F-volatile son, oxidation number of 0, 2, 3, 4 , 5 and 6, the chemical nature of the metal element is very lively, in the humid air combined with oxidation, but also directly with the sulfur, phosphorus, silicon, carbon together.

周期表中Ⅷ族有银白色金属光泽的固体金属过渡元素,原子序数Z=26,原子量55847,化学符号Fe,有一种稳定F同位素5626Fe和一种放射性同位素5526Fe,地壳中含量5%,占元素中第四位、金属中第二位熔点1535℃,沸点2750℃,相对密度786,外围电子结构3d64s2,化学反应时易丢失2—6个电F子,氧化数为0、+2、+3、+4、+5和+6、化学性质很活泼的金属元素,在潮湿空气中能与氧化合,也能直接与硫、磷、硅、碳化合。

The reason why air makes fireburn more intensely was learned only abouttwo hundred years ago, when severalscientists finally proved that oxygen, oneof the gases air contains, can combinewith certain other elements like carbon to release muchheat.

当时某些科学家终于证明,空气中有一种气体叫氧,它能够与其它一些元素化合,从而释放出大量的热。

The reason why air makes fireburn more intensely was learned only abouttwo hundred years ago, when severalscientists finally proved that oxygen, oneof the gases air contains, can combinewith certain other elements like carbon to release muchheat.

参考译文:空气为什么能使火燃烧得更旺?直到大约2 0 0 年前才弄清其原因。当时某些科学家终于证明,空气中有一种气体叫氧,它能够与其它一些元素化合,从而释放出大量的热。

Easy to dissolve in the water, does not dissolve in the organic solvent, water absorbant, absorbs water gradually in the air assumes sticks the porodine, can with the alkali soils metallization synthesis solubility duplicate salt, be one good water softener.

易溶于水,不溶于有机溶剂,吸湿性强,在空气中逐渐吸水而呈粘胶状,能与碱土金属化合成可溶性复盐,是一种良好的软水剂。

He extinguished the candle by a sharp expiration of breath upon its flame, drew two spoonseat deal chairs to the hearthstone, one for Stephen with its back to the area window, the other for himself when necessary, knelt on one knee, composed in the grate a pyre of crosslaid resintipped sticks and various coloured papers and irregular polygons of best Abram coal at twentyone shillings a ton from the yard of Messrs Flower and M'Donald of 14 D'Olier street, kindled it at three projecting points of paper with one ignited lucifer match, thereby releasing the potential energy contained in the fuel by allowing its carbon and hydrogen elements to enter into free union with the oxygen of the air.

38他猛地朝火苗吹去,把蜡烛熄灭。将两把匙形木椅拖到炉边,一把是给斯蒂芬准备的,椅背朝着面临院子的窗户,一把是自己坐的。他单膝着地,往炉格子里放了些粘着树脂的枝条和五颜六色的纸张,以及从坐落于多利埃街十四号的弗罗尔与麦唐纳公司的堆置场以每吨二十一先令的代价买来的优质阿布拉莫木炭。他把这些都十字交叉地堆成不规则的多角形,划了一根安全火柴,在纸张的三个角落点上火。这样,燃料里的碳和氢这两种元素就与空气中的氧气自由化合,散发出潜在的能量。

Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃,沸点560℃,相对密度1935,F外围电子结构为5d46s2,在化学反应时很容易丢掉1—6个电子,也能得到1—2个电子,所以氧化数为0、±1、±2、+3、+4、+5和+6,以+6价化合物最稳定,如WO3不溶于水,空气中的钨会形成薄层三氧化钨保护层,钨能与氟在室温下化合,红热并无潮气时能与溴、碘化合,红热时还能和水反应生成WO3,室温下钨可与王水反应,但热的浓盐酸和硫酸只能与其起微弱反应,但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应,高温下不能与碳、硼和硅反应生成二元化合物,工业上广泛使用钨钢和碳化钨,纯钨用来制灯丝、电子管和X射线管的发热元件,硅化钨可制半导体元件,钨工业生产是将白钨矿石或黑钨矿石精炼。
