- 6. Elements that have the appearance of metals but not all the other properties of metals
- 7. The process of changing state from solid to liquid
- 11. A property of a substance that makes it able to be beaten, bent or flattened into shape
- 16. The process of changing state from gas to liquid
- 17. A shorthand way of writing an element. It always starts with a capital letter, and any other letters are lower case.
- 18. A property of a substance that measures how dangerous it is when absorbed by your body
- 19. Does not allow light to pass through it, like classroom walls
- 21. A shorthand way of representing a compound
- 23. A property of a substance that is an indicator of how easily it catches fire
- 24. Chemical substances that are used up in a chemical reaction
- 25. How well a substance dissolves in a liquid
- 26. A property that describes how a substance combines with other substances to form new chemicals or how a substance breaks up into two or more different substances.
- 29. A chemical change in which one or more new chemical substances are produced. May be described in a word equation.
- 30. The process of adding heat energy which causes particles to move faster
- 33. A property of a substance that means it is able to be drawn into a wire
- 34. Substances made up of two or more different types of atoms that have been joined (bonded) together
- 37. Pure substances made up of only one type of atom
- 38. New chemical substances that are formed in a chemical reaction
Down
- 1. Elements that conduct heat and electricity very well; shiny solids that can be made into thin wires and sheets that bend easily.
- 2. The process of changing state from liquid to solid
- 3. A way of describing a chemical reaction. It has the form reactant + reactant → product + product
- 4. A property of a substance that describes whether light passes through, is partly absorbed or is totally absorbed by the substance
- 5. The process of changing state from liquid to gas that happens only at the surface of the liquid
- 8. The process of changing state from solid to gas.
- 9. A table listing all known elements, grouped according to their properties
- 10. Allows light to pass through completely, like normal window glass
- 12. A property that you can either observe using your five senses, or measure directly without changing the substance being measured.
- 13. Elements that do not conduct electricity or heat. They melt and turn into gases easily and are brittle and often coloured
- 14. Change in which no new chemical substances are formed. This may be a change in shape, size or state. Many of these changes are easily reversible
- 15. Very small particles that make up all things
- 20. The state of matter that has a fixed volume, but no fixed shape
- 22. The process of changing state from liquid to gas that occurs all through the liquid
- 27. Allows some light to pass through it, like frosted glass
- 28. A property of a substance that measures how likely a substance is to take part in a particular reaction
- 31. The state of matter that has no fixed shape and no fixed volume
- 32. Combinations of substances in which each keeps its own properties
- 35. A property of a substance that describes whether it is shiny, glassy, waxy, metallic or dull
- 36. The state of matter that has a fixed shape and volume
