Components of Matter

Matter is composed of different building blocks.

• Atom - Matter is made up of tiny building blocks called atoms. It takes millions and millions of atoms to make even the smallest object.
• Element - Substances made up of a single type of atom are called elements.
• Compound - Compounds are made up of different types of elements.
