CHEMISTRY FOR KIDS A COMPLETE CHEMISTRY GUIDE FOR BEGINNERS Table of Contents Introduction Chapter 1: Chemistry Matters Chapter 2: Basic Elements to Learn Chapter 3: Understanding Elements and its Atomic Structure Chapter 4: Understanding Molecules and Its Formula Chapter 5: Understanding and Creating Your Own Formula Conclusion Introduction Thank you for downloading this book Chemistry for Kids - A Complete Chemistry Guide for Beginners. Many think that Chemistry is a tough subject to learn. But, the truth is, we know a lot about it. We apply Chemistry to everything. In fact, human beings are a result of chemical activity. We understand how Chemistry works instinctively. However, many of us find it difficult to understand and express it in figures. This book introduces Chemistry in a simple way for beginners or young students to understand. It shows the different principles of Chemistry using things that we encounter every day. Also, it encourages many beginners to appreciate the science, instead of being intimidated by it. I hope that you would learn many things and find Chemistry to be fun through this book. Again, thanks for downloading this book, I hope you enjoy it! Chapter 1: Chemistry Matters Chemistry and Its Uses Chemistry is the study of matter and its changes. You may find lengthier definitions in other books, but it is basically the study of atoms as it changes to become matter. Chemistry breaks down matter into elements and determines its composition. It aims to make us understand the established changes and the potential changes that a matter may undergo. But, why must we understand all these? The answer is simple. Everything around us is made of matter and everything is bound to change. The reaction to change by a certain matter can be useful or harmful to another matter. Chemistry helps us categorize and control which reaction can become beneficial or harmful. Thanks to Chemistry, we can develop medicine to cure sickness. We could develop technologies, and produce a variety of products. Matter Before starting with Chemistry, one should first understand what matter is, its states and its parts. Matter is anything that occupies space and has mass. This includes even the objects that have no weight, such as air, light and gases. It usually comes in four states. These are solid, liquid, gas, and plasma. Matters in the solid state are those that take definite shapes and volume. Examples of these are wood, stone, and sand. Those in liquid state have definite volume, but do not have definite shapes. They only follow the shape of their container. Examples of these are water and oil. Gas objects are those that have no definite shape and volume. They could not be contained, unless they are compressed. Air and helium are only a few objects in gas form. The plasma state does not exist in Earth, but in outer space. However, some scientists create artificial objects in this state. Examples of objects in plasma state are lightning and neon lights. Elements and Compounds Matter may be composed of a single element or a combination of elements. An element is the smallest unit of matter, which could no longer be divided. Examples of elements are gold, silver, and oxygen. As of today, scientists have discovered about 118 different elements. Earth produces or houses 98 of these elements. The scientist, Dmitri Mendeleev, started listing these elements in a periodic table. A compound is composed of two or more elements. These elements are bonded together chemically, to create another matter. Water is one of the basic examples of a compound. Two elements, hydrogen and oxygen, are bonded together to create water.
