在新课程实施的今天,中考化学命题已改变了过去的偏、难、怪的试题,随之而来的与“新”有关的试题层出不穷,现举例分析。一、与新规定有关例1(2013年娄底市)2013年1月19日,《国际防治汞污染公约》发布。图1为元素汞的信息,从图中获得的信息正确的是()。图1A.汞属于非金属元素B.汞的核电荷数为80C.汞的相对原子质量为200.6 g D.在化学反应中,汞原子容易得到电子解析本题以防治汞污染公约为背景命题,
In the new curriculum implementation today, the senior high school entrance examination chemistry thesis has changed the past partial, difficult, strange examination questions, followed by “new” related questions after another, is an example analysis. I. Related to the New Regulations 1 (Loudi, 2013) On January 19, 2013, the “International Convention for the Prevention of Mercury Pollution” was promulgated. Figure 1 is the elemental mercury information, the information obtained from the figure is correct (). Figure 1A. Mercury is a non-metallic element B. The nuclear charge of mercury is 80 C. The relative atomic mass of mercury is 200.6 g D. In the chemical reaction, the mercury atom is easily electronically resolved. This question takes the prevention of mercury pollution as the background proposition,
