金属活动性顺序是金属化学性质的重要体现,也是初三化学学习的重要内容之一.在人教版教材中,第八单元的课题二以金属与氧气反应引出金属的第一种化学性质,并且告诉读者:实验表明,大多数金属都能和氧气发生反应,但反应的难易程度和剧烈程度是不同的.其次以金属与盐酸、稀硫酸反应,指导学生观察反应的能否发生以及剧烈程度.最后以铁钉放入硫酸铜溶液为例,通过观察反应,总结反应发生的条件,得出金属 Metal activity sequence is an important manifestation of the chemical nature of the metal, but also one of the important content of the third chemical learning.In the PEP textbook, the eighth unit of the second theme of the reaction of metal and oxygen leads to the first chemical properties of metals, And told the reader: Experiments show that most metals can react with oxygen, but the reaction difficulty and severity are different.Second, the metal and hydrochloric acid, sulfuric acid reaction to guide students to observe the reaction can occur and intense Degree.Finally, take the iron nails into the cupric sulfate solution as an example, by observing the reaction, summarizing the conditions of the reaction, the metal
