Sodium
钠
 | Sodium, like the other alkali metals (Group I), is a sivery-white metal of very high chemical reactivity.
钠与其他碱金属（第I组）一样，是一种银白色、化学活性极高的金属。
Sodium is one of the big 8 elements in the Earth's crust, being the sixth most abundant element at about 2.8% by weight. It is a constituent of the plagioclase form of feldspar, one of the most abundant minerals on the earth.
钠是地壳中八大元素之一，是地壳中第六 abundant 的元素，约占2.8%（按重量计算）。它是斜长石的一种组成成分，是地球上最丰富的矿物之一。

The most important compound of sodium is sodium chloride, NaCl (common table salt). It crystallizes as colorless cubes. Comprising 3% of sea water and also occurring in large solid deposits and underground salt brines, NaCl is an abundant mineral. In crystalline form it is given the mineral name halite. It is important as an electrolyte in human blood and plasma, which contain about 0.9 grams of NaCl per 100 ml.
钠最重要的化合物是氯化钠，NaCl（普通食盐）。它以无色立方晶体形式结晶。它占海水的3%，也存在于大型固体矿床和地下盐水之中，NaCl是一种丰富的矿物。以晶体形式存在时，它被赋予矿物名称——石盐。它在人体血液和血浆中作为电解质起重要作用，其中含有约0.9克NaCl每100毫升。
Sodium chloride is used for the extraction of metallic sodium and gaseous chlorine, as well as for preparation of other compounds of these elements.
氯化钠用于提取金属钠和氯气，以及制备这些元素的其他化合物。
Sodium borates such as borax (sodium tetraborate decahydrate, Na2B4O7. 10H2O), kernite (sodium tetraborate tetrahydrate, Na2B4O7. 4H2O), and colemanite (calcium hexaborate pentahydrate, Ca2B6O11. 5H2O) along with tincalconite form vast deposits of boron in California .
如硼酸钠（硼砂，十水合四硼酸钠，Na₂B₄O₇·10H₂O）、肯纳石（四硼酸钠四水合物，Na₂B₄O₇·4H₂O）和科拉明石（钙的五水合六硼酸盐，Ca₂B₆O₁₁·5H₂O）以及廷卡诺石，这些物质在加利福尼亚州形成了大量的硼矿藏。 Sodium sulfate is found in mineral form as Thenardite.
硫酸钠以Thenardite的形式存在于矿物中 A phosphate of aluminum and sodium is Wardite.
Sodium hydroxide (NaOH) is a very important laboratory reagent and a widely used industrial chemical. Called caustic soda, it is very corrosive to the skin. It is used in the manufacture of soap, the refining of petroleum, the manufacture of paper, textiles, rayon, cellulose film, and many other products.
氢氧化钠（NaOH）是非常重要的实验室试剂，也是广泛使用的工业化学品。它被称为烧碱，对皮肤有很强的腐蚀性。它用于肥皂的制造、石油精炼、纸张、纺织品、人造丝、 cellulose 胶片以及许多其他产品的生产。
The properties of liquid sodium metal make it useful as a coolant in fast breeder reactors and as a heat transfer agent for very high temperature reactions.
液态钠的特性使其成为快中子堆反应堆中的冷却剂，以及用于非常高温反应的传热介质。
