I believed that I have mastered every concept pretty well. For instance, some concepts taught that I learned was how to classify matter, how to identify elements, how to do an electron configuration, how to distinguish between a physical and chemical change. There are three states of matter: solid, liquid, and gas. A solid has a definite shape, definite volume, and has no compressibility. A liquid has indefinite shape, definite volume, and no compressibility. In addition, gas has indefinite shape, indefinite volume, and compressibility. Furthermore, in order to identify elements, one will have to look at the atomic number, therefore, establishing the number of protons. Last but not least, a chemical change is a change in a substance
