元素的很多性质都与其原子的核外电子层结构有关,比如金属性非金属性、化合价、相关化合物的类别及性质等;另外,中学化学中很多内容的微观解释也都要用核外电子的相关知识来说明,比如氧化还原反应、金属的熔沸点、晶体的结构等等.因此高考命题常在这些知识的交叉点上做文章,以考查学生灵活应用知识的能力.本文笔者将高考中有关这方面试题的常见题型作了简单的归纳和解析,供同学们在学习时参考 Many of the properties of the element are related to the structure of the outer nuclear electronic layer of its atom, such as the metallic nonmetallurgy, valence, the type and nature of related compounds, etc.; in addition, the microscopic interpretation of many contents of middle school chemistry also requires the use of extranuclear electrons. Related knowledge to illustrate, such as redox reactions, the melting point of the metal, the crystal structure, etc. Therefore, the college entrance examination proposition often fusses at the intersection of these knowledge to examine students’ ability to use knowledge flexibly. This article will be related to the college entrance examination The common questions in this area are briefly summarized and analyzed for the students to learn
