常见无机物及其应用是高中化学必修课程“化学1”的重要内容。《普通高中化学课程标准(实验)》(以下简称《课程标准》)对该内容的处理是从元素分类的角度选择元素,并根据元素在周期系中的代表性、自然界中的广泛性以及对生产生活与环境保护的广泛影响,选取了四种金属元素(钠、铝、铁、铜)和四种非金属元素(氯、氮、硫、硅)的单质及其重要化合物(见图1)。
Common inorganic and its application is an important part of high school chemistry curriculum “Chemistry 1 ”. The content of “Ordinary High School Chemistry Curriculum Standard (Experiment)” (hereinafter referred to as “Curriculum Standard”) is to deal with the content by selecting the elements from the perspective of element classification and according to the representativeness of the elements in the periodic system, the universality in nature, Production and living and environmental protection, we selected single elements and their important compounds from four kinds of metal elements (sodium, aluminum, iron and copper) and four non-metallic elements (chlorine, nitrogen, sulfur and silicon) .
