课程名称：物质的粒子性质 课程概述：本课程介绍物质的粒子性质，阐述物质的定义及其在宇宙中的重要性。物质是具有质量并占据空间的任何东西，几乎宇宙中的所有事物都是由物质构成的，包括植物、动物、我们吃的食物、喝的水，甚至是我们呼吸的空气。课程旨在以更易理解的方式教授化学知识，以便学生能够更好地吸收相关内容。教师分享了多年的教学与研究经验，并指出传统化学教学中存在的问题，如学生对常见化合物（如氯化钠）的误解。课程的教学方法强调“让化学变得简单”，帮助学生掌握化学知识，从而更好地理解化学工业如何利用其他化学物质生产化学产品。 本课程内容包括： - 物质是由原子、分子和离子等基本粒子构成的。 - 物质的物理性质与化学性质的分类介绍。 - 物理变化与化学变化的区别。 - 分子、原子、离子及其原子性定义。 - 轨道的概念及电子在轨道中的分布。 通过本课程，学生将掌握物质的基本概念，为深入学习化学打下良好基础。
PARTICULATE NATURE OF MATTER.What is matter; matter is anything that has mass and occupies space. By definition, we see that almost everything in the universe is made of matter. Examples of matter include the plants and animals around us; the food e we eat, the water we drink and even the air we breaths. We ourselves are matter.But then, chemistry class should be presented to students in such a way they will understand it better. This is what I discovered in my years of teaching and research experience.Years ago i encountered experience with some chemistry students in a full school. When I walked into a Home Economics laboratory where they were taking some classes on how to cook some foods. Then, I asked a students to bring sodium chlorine to add to the food. They where all surprised. Thinking I wanted to harm them. That sodium chloride is poisonous. Statistically, 95% of students failed. They all learnt for the very first time the cooking salt which is the normal salt is what they see or hear almost everyday in chemistry classroom.A good logical approach will make students to find chemistry easier. My methodology ‘'Make Chemistry Easy''.The knowledge in chemistry helps chemical industry to make chemicals from other chemical substances.This Lectures features:In general, matter is built up of one or more of the following elementary particles; atoms, molecules, and ions.. Sugar is a white solid which dissolves in water and tastes sweet. While iron has a metallic luster; it may be magnetized and rusts with the formation of a reddish deposit.
