Across
- 5. Take the shape of their container, particles slide past each other, and have medium energy levels.
- 6. A substance in which there is only one type of particle. Examples: elements and compounds like gold, copper, water, and carbon dioxide.
- 7. A property of matter that describes a substance based on its ability to change into a new substance with different properties.
- 9. A change that occurs when one or more substances change into entirely new substances with different properties.
- 12. Anything that has mass and takes up space
- 14. A single piece of a compound made from non-metals. Examples: 1 water molecule, 1 CO2 molecule, 1 sugar molecule.
- 15. A change in a substance that doesn't involve a change in the identity of the substance.
- 16. The smallest particle into which an element (matter) can be divided. Made up of protons, neutrons, and electrons.
Down
- 1. A property of matter that can be observed or measured without changing the identity (chemical makeup) of the matter.
- 2. A mixture where the different components are easily seen. Examples: muddy water, salad dressing.
- 3. A lot like a gas but particles are electrically charged and has extremely high levels of energy
- 4. Spread out to fill the entire space given, particles move independently of one another, and have high levels of energy.
- 8. A pure substance that cannot be broken down into simpler substances. Examples: hydrogen, oxygen, uranium, neon.
- 10. Has the same appearance and properties throughout the mixture. Looks like it is made up of only 1 substance, but the particles of multiple substances are evenly spread out through the whole thing. Examples: solutions, milk.
- 11. A combination of 2 or more substances that are not chemically combined. They CAN be separated by physical means. Examples: pizza, chicken noodle soup, salad dressing.
- 13. Have definite shape and volume, particles are packed tightly together, and have low energy levels.
