**课程名称：** 化学 - 氢 (Chemistry - Hydrogen) **课程概述:** 本课程深入探讨了氢这一独特而重要的元素。作为自然界中原子结构最简单的元素，氢在原子状态下仅由一个质子和一个电子组成，而在元素状态下，它以双原子的形式（H2），即二氢存在。氢能够形成比其他任何元素都多的化合物。课程强调了氢作为能源的巨大潜力，尤其是在应对全球能源问题的背景下。此外，课程还将介绍氢的工业重要性。 **核心内容摘要:** * **氢的独特性:** 氢是最轻的原子，只有一个电子，失去电子后即为质子，因此具有独特的化学性质。 * **同位素:** 氢有三种同位素：氕 (protium, 1 1H)、氘 (deuterium, D or 2 1H) 和氚 (tritium, T or 3 1H)。其中只有氚是放射性的。 * **元素周期表中的位置:** 尽管氢在化学性质上与碱金属和卤素都有相似之处，但由于其独特的性质，它在元素周期表中占据了一个独立的位置。 * **丰度:** 氢是宇宙中最丰富的元素。在地球大气中，游离态的氢含量极少，但在地表化合物中，它是第三丰富的元素。 * **工业制备:** 工业上，二氢主要通过石化产品的“水煤气变换反应”制备，也可通过电解盐水（brine）作为副产物获得。 **课程具体内容包括：** * 二氢的用途 * 过氧化氢的用途 * 氢与碱金属、卤素的相似性 * 氢的同位素、同素异形体和分子形式 * 水的简介 * 氢的物理和化学性质 * 氢化物 * 水的化学性质 * 过氧化氢的物理性质 * 过氧化氢的强度 * 水的结构 * 重水的效应和用途 * 过氧化氢的制备 * 重水 * 硬水和软水 * 水的硬度去除 * 氢与卤素的差异点 * 过氧化氢的浓度及其储存
DescriptionHydrogen has the simplest atomic structure among all the elements around us in Nature. In atomic form it consists of only one proton and one electron. However, in elemental form it exists as a diatomic (H2) molecule and is called dihydrogen. It forms more compounds than any otherelement. Do you know that the global concern related to energy can be overcome to a great extent by the use of hydrogen as a source of energy? In fact, hydrogen is of great industrial importance as you will learn in this unit.SUMMARYHydrogen is the lightest atom with only one electron. Loss of this electron results in an elementary particle, the proton. Thus, it is unique in character. It has three isotopes, namely: protium (1 1H), deuterium (D or 2 1H) and tritium (T or 3 1H). Amongst these three, only tritium is radioactive. Inspite of its resemblance both with alkali metals and halogens, it occupies a separate position in the periodic table because of its unique properties. Hydrogen is the most abundant element in the universe. In the free state it is almost not found in the earth's atmosphere. However, in the combined state, it is the third most abundant element on the earth's surface.Dihydrogen on the industrial scale is prepared by the water-gas shift reaction from petrochemicals. It is obtained as a byproduct by the electrolysis of brine.Course ContentUses of DihydrogenUses of Hydrogen PeroxideResemblance with Alkali Metals and HalogensIsotopes ,Allotropes & Molecular forms of HydrogenWater - IntroductionPhysical and Chemical Properties of HydrogenHydridesChemical properties of waterPhysical Properties of Hydrogen PeroxideStrenth of Hydrogen peroxideStructure of WaterEffects and Uses of Heavy WaterPreparation of Hydrogen PeroxideHeavy WaterHard & Soft WaterRemoval of Hardness of WaterDissimilarities of hydrogen with halogensConcentration of Hydrogen peroxide ans its storage
