补充资料:汞(Hg)
分子式:
分子量:
CAS号:

性质:俗称水银(因其如银似水而得名)。周期系第Ⅱ族副族(锌族)元素。原子序数80。稳定同位素:196,198,199,200,201,202,204。原子量200.59。是在常温下唯一的液体金属。银白色,易流动。密度13.546。熔点-38.87℃。沸点356.72℃。化合价+1和+2。在常温下不被空气氧化,加热时愧疚化为氧化汞。汞的蒸气有剧毒!有溶解许多金属的能力,所构成的合金统称汞齐。易溶于硝酸,也溶于热浓硫酸,但与稀硫酸、盐酸、碱都不起作用。用于制造物理仪器(如气压计、温度计等)、药物、汞蒸气灯、汞整流器、汞齐、电极、催化剂、金与银的提取、补牙的银汞齐、农药和雷酸汞等。自然界中主要成辰砂(HgS)而存在,也有少量自然汞。可将辰砂加少许碳在空气中加热而制得。
