- 4. The base unit of volume in the metric system. Abbreviated "L"
- 6. The basic building block of matter. Cannot be broken into smaller pieces using chemical reactions or physical changes.
- 8. The substances that go into a chemical reaction. These are on the left side of the arrow in a chemical equation.
- 12. A substance made up of only one kind of atom. Organized in the Periodic Table.
- 14. A tool used to measure the mass of objects, usually in grams.
- 15. The study of atoms including the ways in which they interact, combine, and change, and the use of these processes to form new substances.
- 17. Electron Any electron in the outermost electron level of an atom.
- 18. The property of metal that means it allows heat and electricity to flow through it.
- 20. The number in an element’s tile on the periodic table that tells you how many protons that elements have.
- 21. The property of metal that means it’s shiny.
- 22. The connecting point between atoms in a molecule. Different types of bonds are possible such as covalent, single, double, triple, and ionic.
- 23. A process that is used by scientists and others in order to solve problems and find answers in a logical way.
- 24. A measure of how much mass is in a certain volume. Units are usually g/mL or g/cm3.
- 26. The positively charged subatomic particle that exists in the nucleus of an atom.

- 1. A family of elements in the periodic table made up of the most reactive non-metals. These have 7 valence electrons.
- 2. Dimitri ________ - The scientist who organized the known elements into the periodic table.
- 3. A tube-like piece of lab equipment that is used to precisely measure liquid amounts, usually in milliliters (mL).
- 5. The amount of space that something takes up.
- 7. A physical substance that occupies space.
- 9. The negatively charged subatomic particle that orbits around the outside of the nucleus of an atom.
- 10. A system of measurement that relies on decimals rather than fractions. The basic units are meters, liters, and grams.
- 11. The base unit of mass in the metric system. Abbreviated "g"
- 13. The neutrally charged subatomic particle that exists in the nucleus of an atom.
- 15. The Law of _____________ of Mass is a scientific principle that states that matter cannot be created nor destroyed, only changed from one state to another.
- 16. The base unit of length in the metric system. Abbreviated "m"
- 19. The philosopher who first said that matter is composed of relatively simple particles that are too small to be visible to the naked eye. He called these particles “atoma”.
- 25. Particle made up of two or more bonded atoms.
- 26. The substances that come out of a chemical reaction. These are on the right side of the arrow in a chemical equation.
