元素周期表和元素周期律是高中化学基本理论之一,它将高中化学中一些貌似无关的非金属元素如氮、硫、氯和金属元素如钠、铝、铁等依据结构、位置、性质三者之间的本质联系和递变规律对号入座、紧密联系为一个统一的有机整体.如何让学生掌握元素周期表和元素周期律的科学本质,形成具有严密逻辑链条的元素观,对于元素化合物知识的学习具有重要意义.一、问题的提出对于元素周期表与周期律的教学,常见的教学方法有这样 The Periodic Table of the Elements and the Periodic Law of the Elements are one of the basic chemistry theories of high school chemistry. Some of the seemingly unrelated nonmetallic elements in high school chemistry such as nitrogen, sulfur, chlorine and metal elements such as sodium, aluminum and iron are classified according to the structure, position, How to make students master the scientific nature of the periodic table of elements and the periodic law of the elements to form the elemental view with strict logic chain and to understand the knowledge of elemental compounds Learning is of great significance. First, the question raised For the periodic table and periodic law teaching, common teaching methods have this
