化学是研究物质的一门自然科学.化学基础知识分为理论和元素化合物两部分,它们密切配合、相辅相成.理论知识以元素化合物知识为基础,如果没有元素化合物做知识结构的“骨架”,理论的学习必然脱离实际,成为无本之木、无水之源;如果没有生动实际的元素化合物知识依托,就不可能发展智力,培养能力.
Chemistry is a natural science for the study of matter. Basic knowledge of chemistry is divided into two parts: theory and elemental compounds. They are closely related to each other and complement each other. Theoretical knowledge is based on the knowledge of elemental compounds. If no elemental compound is used as the “skeleton” of the knowledge structure, theory The study will inevitably be divorced from reality, and it will be the source of wood without water and water; if it is not supported by vivid and practical knowledge of elemental compounds, it will be impossible to develop intelligence and cultivate abilities.
