Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only oxygen and fluorine.

氯气（chlorine）是 氯 元素形成的一种 单质，化学式Cl2。 常温常压下为黄绿色、有强烈刺激性气味的剧毒气体，具有窒息性，密度比空气大。 可溶于水和碱溶液，易溶于有机溶剂，难溶于饱和食盐水 [6]。 易压缩，可液化为黄绿色的油状液氯。 氯气具有毒性，主要通过呼吸道侵入人体，可溶解在上呼吸道黏膜所含的水分里，会对黏膜造成损害。 氯气中混合体积分数为5%以上的氢气时遇强光可能会有爆炸的危险。 氯气是 氯碱工业 的主要产品之一，能与有机物和无机物进行取代 …

Chlorine is a green yellow gas with a very pungent odour that is twice as dense as air. It is a chemical element that belongs to the halogen group with the symbol Cl. It was discovered in 1770’s and soon became useful as a commercial agent. It is found easily in its natural state.

氯气 是 卤族元素 氯 的 单质 形式， 化学式 为 。 氯 元素在元素周期表中位于 氟 和 溴 之间，氯气的性质也大多处于氟单质和溴单质之间。 瑞典 化学家 卡尔·威廉·舍勒 （Carl Wilhelm Scheele）在1774年使用 盐酸 与 软锰矿 通過下述反应制得 氯氣： 继舍勒之后，贝托雷对氯气进行了更加深入的研究。 发现将氯气通入 水 中会有盐酸生成，同时还伴随着有能使带火星木条复燃的气体（氧气）放出。 所以他认为氯气中含有氧，但尝试用当时已知的还原剂像 金属 、 木炭 、 磷 等还原 …
