必修一中学习了金属元素和非金属元素的物理及化学性质.通过做实验,我们观察到许多有趣的实验现象,同时学会了许许多多的化学方程式.但是,我们同时也遇到一个难题,那就是高考中必考的一类型题—推断题.金属、非金属以及其化合物,物质种类繁多,而它们之间的反应更多.同时,物质的颜色,反应的条件变化多端,使得推断题变化莫测,难上加难.从教学实践中我们发现,将金属、非金属及其化合物的共性,以及反应方程式的特点等等进行归纳总结,学生方便记忆,也方便灵活的应用.因此,本文从以下五个方
Compulsory one to learn the physical and chemical properties of metal elements and non-metallic elements through experiments, we observed many interesting experimental phenomena, while learning a lot of chemical equations.However, we also encountered a problem, That is the type of exam to be taken in the college entrance examination - inference questions .Metal, nonmetal and its compounds, a wide range of substances, and more reaction between them .At the same time, the material color, reaction conditions changeable, making inference Unpredictable and unpredictable, from the teaching practice, we found that the metal, non-metallic compounds and their commonalities, as well as the characteristics of the reaction equation and so summarized, students easy to remember, but also convenient and flexible application.Therefore, This article from the following five parties
