分子模型(包括离子模型、晶体模型等)能够直观反映分子、离子或晶体的结构特征,所以在化学学习和研究中常用分子模型图来表征分子、离子或晶体的结构。基于此,化学学科中出现了一类以分子模型图(包括离子模型图、晶体结构模型图等)或由此衍变而来的图像作为命 Molecular models (including ion models, crystal models, etc.) can directly reflect structural features of molecules, ions or crystals. Therefore, molecular models are commonly used in chemistry learning and research to characterize structures of molecules, ions or crystals. Based on this, a class of chemical images emerged as a result of molecular model diagrams (including ion model diagrams, crystal structure model diagrams, etc.)
