SCIENCE VOCABULARY

4. A substance that conducts electricity at high temperatures, but not at low temperatures.
7. A state of matter that has no definite shape, but has a definite volume.
9. Ability of metals and alloys to be rolled or hammered into thin sheets.
10. Group of elements that may be solids, liquids, or gases at room temperature and tend to be poor conductors of heat at electricity, and NOT malleable, ductile, or lustrous; most are gases.
14. Property of metals and alloys that describe having a shiny appearance or reflective light.
15. Measurement of the mass of an object divided by it's volume.
16. Elements in Groups 3-12 of the Periodic Table; occur in nature in uncombined elements and include the iron triad and coinage metals.
17. Completely nonreactive of nonmetals in Group 18; all are gases at room temperature.
19. Any characteristic of material, such as size or shape, that you can observer or attempt to observe without changing the identity of the material.
21. Element that typically is a hard, shiny solid, is malleable, and is a good conductor of heat and electricity.

1. Maximum amount of a solute that can be dissolved into an amount of solvent at a given temperature.
2. Elements that have properties of both metals and nonmetals on the Periodic Table that separate metals from nonmetals along a zigzag line; they are semiconductors.
3. The amount of matter in an object
5. Any characteristic of a substance, such as flammability, that indicates whether it can undergo a certain chemical change.
6. Any metal in Group 2A of the Periodic Table
8. The amount of space occupied by an object
11. Silvery solids with low densities and low melting points, Found in Group 1
12. A form of matter that has a definite shape and volume.
13. A form of matter that takes both the shape and volume of it's container.
18. Ability of metals or alloys to be pulled into wires.
20. Highly reactive nonmetals found in Groups 17 of the Periodic Table.
