Matter

2. Smallest particle of an element that still has the element’s properties
3. Amount of matter in a substance or object
6. Homogeneous mixture with tiny particles- salt water; particles are too small to reflect light/see
7. Anything that has mass and volume
8. Can be observed or measured without changing the composition of matter
12. Unique substance that forms when two or more elements combine chemically
13. Homogeneous mixture with medium-sized particles- milk and gelatin; particles are large enough to reflect light/see, but too small to settle or filter out of the mixture
14. How closely packed are the matter particles
15. Amount of space matter takes up
16. Can be measured or observed only when matter undergoes a change to become an entirely different substance

1. Smallest particle of a compound that still has the compound’s properties
3. Combination of two or more substances in any proportion
4. Measure of the force of gravity pulling on an object
5. Pure substance that cannot be separated into any other substances
9. Heterogeneous mixture with large particles- muddy water; particles are large enough to reflect light/see AND will settle or filter out of the mixture
10. Ability of matter to combine chemically with other substances
11. Ability to burn
13. Rigid, lattice-like framework of many atoms or molecules bonded together
