ATOMIC STRUCTURE
In many ways, this lesson is the start of your journey into chemistry. In this foundational lesson, we will learn about the building blocks of matter: atoms. Alchemists, the precursors to chemists, had a saying: “As above, so below”. A modern interpretation of this saying is that the properties of what we can see can help us understand the properties of what we cannot. In this lesson, we will learn how the properties of atoms determine the properties of the world around us.
MATTER
If I were to put the daisy on a scale, it would have a mass. The flower would also occupy a measurable amount of space, meaning it has volume. As the daisy would have both mass
and volume, it would be considered matter. On the other hand, the image of that daisy would not be considered matter as the image has no mass, and therefore, is not considered to be matter. Instead, the image is made of energy. If power were to suddenly stop flowing to your screen, you would no longer see the image as the light hitting your eye would no longer be coming from the screen.
We can also see that the matter surrounding us is not all the same. Water has very different properties from plastic which, in turn, has different properties from wood. As we see here, the term matter is a very broad term, and we can sort matter into different categories; however, to do this, we must first look at the building blocks of our universe: atoms.………..
