atom	Atoms are very tiny things in the universe. We cannot see them with our eyes, but they make up everything around us and in space.

Each of these elements is made up of a different kind of atom.

chemical	Chemicals are the different substances that exist on the earth and in space. A chemical can be one basic substance, such as oxygen or gold or iron, but we also use the word chemical when we talk about mixtures of things, such as gasoline.

Chemicals are things that we can find in nature, but chemicals can also be substances that scientists make for special purposes, such as for medicines or products that we use in our daily lives.

chemical element	Everything in our world and in space is made up of different chemical elements. Things like oxygen, lead, iron, and gold are some of these elements. Chemical elements are the very simple building blocks of all other things. They are pure substances. That means that they are made up of only one type of thing--one type of atom. The element iron, for example, is made up of only atoms of iron. It's not mixed with anything else. The chemical elements do mix with other chemical elements, though. That's how we get things like water, which is made up of two elements: oxygen and hydrogen.
chemistry	Chemistry is one of the sciences. In chemistry, people study the basic substances that all things are made of. Iron, oxygen, and gold are some examples of basic substances. In chemistry, people also study what happens when they put basic substances together.
