Across
- 3. - Property allowing a metal to be hammered into thin sheets
- 5. - Slow surface degradation of a metal from moisture, air or acid
- 9. - Principal ore from which aluminium is extracted
- 11. - Unwanted rocky/earthy impurities mixed with an ore
- 12. - Type of oxide, like aluminium's, that reacts with both acids and bases
- 13. - Heating a sulphide ore strongly in excess air to convert it to an oxide
- 14. - Homogeneous mixture of metals with deliberately altered properties
Down
- 1. - Heating a carbonate ore strongly in limited/absent air
- 2. - Property allowing a metal to be drawn into thin wire
- 3. - The only metal that is liquid at room temperature
- 4. - Alkali metal stored in kerosene owing to its violent reaction with water
- 6. - Electrode where impure metal dissolves during electrolytic refining
- 7. - Combining capacity determined by electrons lost, gained or shared
- 8. - Bond type formed when a metal's valence electrons are transferred to a non-metal
- 10. - Non-metal that forms allotropes; graphite breaks the non-metal "no conduction" rule
