金属元素Na、Mg、Al、Fe及其化合物是元素化合物知识的重要组成部分,是构成中学化学知识的基础,也是学好基本理论知识的重要前提。虽然这部分知识比较具体、直观,容易接受,但由于这部分内容比较庞杂、零散,复习时学生常感到单调、枯燥,难以记忆或记不牢,所以良好的复习策略显得非常重要。

The metal elements Na, Mg, Al, Fe, and their compounds are important components of the knowledge of elemental compounds. They are the basis for the formation of chemical knowledge in middle schools and are also an important prerequisite for learning basic theoretical knowledge. Although this part of the knowledge is more specific, intuitive, and easy to accept, but because this part of the content is more complex and fragmented, students often feel monotonous, boring, difficult to remember or not remember when reviewing, so a good review strategy is very important.
