众所周知，化学基本概念是化学事实、化学原理、化学方法、化学技能等构成化学知识体系之“纽结”。新编教柱中的58个基本概念中，有一半多被称为“奠基性概念”，如原子、分子、相对原子质量、式量、元素、单质、化合物、纯净物、混合物、氧化、还原等，毫不夸张地优，它们也? As we all know, the basic concept of chemistry is the “knot” that constitutes the chemical knowledge system, such as chemical facts, chemical principles, chemical methods, and chemical skills. More than half of the 58 basic concepts in the newly-edited teaching column are called “foundational concepts” such as atoms, molecules, relative atomic masses, formulae, elements, simple substances, compounds, pure substances, mixtures, oxidation, and reduction. And so on, it’s no exaggeration to be excellent, are they?
