    摘要(Abstract):

    高中化學選擇性必修2模塊《物質結構與性質》理論性很強、內容抽象,許多學生對多電子原子的核外電子排布規律的掌握不太好.教學時可以利用n+0.7l規則進行推演,將抽象知識形象化、繁瑣內容簡便化以方便學生記憶,減輕學生學習時的畏難情緒.同時,n+0.7l規則可使學生更熟練的書寫多電子原子核外電子排布.
    The "material structure and property" as an optional chemistry course for senior high-school students is highly theoretical and abstract, and it is difficult for the students to understand the arrangement of extra-nuclear electrons of multi-electron atoms. This research proposes that the(n+0.7l) rule can be used for deductive analysis in teaching, because it can not only visualize the abstract knowledge and simplify the tedious content, but also facilitate the memory and reduce the students′ fear of difficulties in learning. Meanwhile, the(n+0.7l) rule can make the students more proficient in writing the extra-nuclear electron arrangement of multi-electron atoms.
