Across
- 2. how close particles are packed together
- 5. a usually reversible change in the physical properties of a substance, as size or shape
- 7. detected by the senses or can be identified without a chemical reaction
- 8. a measure of the amount of matter in an object
- 10. elements on the left side of the periodic table that are typically solid, dense, hard, shiny, malleable and good conductors.
- 12. elements have properties in between metals and nonmetals, they can be shiny or dull, their shape can change easily, and can carry an electrical charge.
- 14. particles in a mixture that are distributed unevenly
- 15. a material that is composed of only one type of particle
- 18. substances with different properties from the different elements its made up from
- 19. elements mostly on the right with no luster, are poor conductors, not ductile or malleable, and break easily.
Down
- 1. mixtures that are homogeneous, and have very small particles that don’t settle
- 3. substances that can't be broken down
- 4. a scattering of light in a colloid or fine suspension
- 6. a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance
- 9. composed of more than one substance
- 11. heterogeneous mixtures that have large particles that settle
- 13. ability of a substance to form a new substance
- 16. particles in a mixture distributed evenly
- 17. homogeneous mixtures that have medium sized particles that don’t settle
