Across
- 6. (same throughout) that is made up of two or more different elements bonded together. For example H20 all water molecules are made the same
- 9. a chart of all known elements on Earth organized based on the physical and chemical properties of each
- 11. change in form or appearance but not chemical make up
- 13. the big number in front of a formula that indicates how many molecules groups
- 15. consists of multiple different substances that are evenly distributed so each sample of the mixture will have the same proportions of components
Down
- 1. a set of chemical symbols (letters) and subscripts (numbers) showing which elements are bonded together to form a molecule
- 2. a letter abbreviation of an element name; always starts with a capital letter
- 3. describes a chemical reaction by showing how atoms in the reactants are rearranged to form a new substances in the product
- 4. substances formed as a result of a chemical equation (Right side)
- 5. During a reaction a new substance is made when the atoms of the original substances are rearranged to make something new (evidence: Precipitate, energy change, gas, and sometimes color)
- 7. the smallest particle of matter that has distinct properties because of its nucleus which contains protons and neutrons and an electron cloud
- 8. the starting materials found in a chemical equation (left side) that will react together
- 10. consists of multiple different substances that are not evenly distributed so each sample of the mixture may have different proportions of components
- 12. a substance is evenly distributed (or dissolved) with a liquid, gas, or solid
- 14. a pure substance (same throughout) that is made up of one type of atom
