绪论

什么是化学？我们为什么要学习和研究化学？化学的发展历程是什么？对这些问题的回答可以帮助我们对化学有一个初步但具体的认识。随着后续学习的深入，我们也会进一步加深对上述问题的理解。

原子结构

原子及亚原子粒子是物质世界的基础。从提出原子这个概念开始，人类经历了上千年才开始对原子结构有了更深入的理解。随着认识的深入，人们逐渐发现原子这种微小粒子具有奇妙的结构特征，而这些发现已经成为人类认识和理解自然现象的起点。

分子结构

分子以及分子中的化学键是化学的核心内容。搞清楚到什么是化学键以及为什么会存在化学键，对于理解化学的理论体系（以及名词体系）至关重要。前人对这两个问题的探索可以给我们很多启发。

气体

对于气体这种生活中经常遇到的相态，甚至包括气体定律，你都不会感到陌生。所以这部分知识的要点是气体分子运动论——一个可以把气体的统计性质展现出来的理论。

分子间作用力

分子间作用力，在化学领域里可以说是无所不在。在过去半个世纪以来，化学工作者对化学键和分子结构已经有了相当好的认识，但是对分子间作用力的认识才刚刚开始。由于这种相互作用力的普遍存在，使得这个领域成为化学中各个分支学科的交汇点之一。

期中考试

化学动力学

化学的核心内容是化学反应以及与化学反应有关的结构和能量变化。在过去二、三十年里，化学动力学领域有了突破性的进展，一系列先进的技术（如时间分辨、原位探测等）被应用于化学反应历程和机理研究，使我们对一些传统的化学反应有了全新的认识。

化学平衡

成语“物极必反”是对化学平衡的最好描述：两个相反的作用最终会达到某种平衡。化学平衡反映了化学反应的限度。在化学实验室中经常能观察到这类平衡过程，因此如何描述这些现象以及如何利用化学平衡性质判断反应的方向是化学工作者的基本功。

溶液中的平衡

溶液是化学的主要对象之一，同时溶液中的反应过程与化学平衡密切相关。前人已经积累了大量关于溶液中化学平衡的知识，如酸碱平衡、沉淀溶解平衡等。对这些平衡过程的理解可以帮助我们更好地认识化学的基本规律。

化学热力学

化学的经典理论主要包括两个部分，一是动力学，二是热力学。前两章中的化学平衡其实就是热力学的知识。本章将探讨更基本的热力学概念以及它们在化学中的应用。热力学是一个强大的理论工具，大量的宏观化学现象都可以应用热力学原理进行讨论。

电化学

在化学中，电的现象与它在物理中同样重要。也可以说，化学与物理在电化学领域交汇在一起。目前，由于新能源（例如太阳能电池、光电转化、电致发光等）已经是最重要的科技前沿之一，因此电化学也广受重视。近年来，电化学领域取得了很多重要的进展。
