- 1—C.3
- 2Why is GOLD found in the Earth as a metal?Because it is so unreactive
- 3What is the name for rock that is mined were the metal can be extracted economically?An Ore
- 4What are the typical properties of 'Transition Metals'The elements in the centre of the periodic table, between groups 2 and 3, are called the transition metals. The metals are Good for building with and making things, strong and malleable. Most are alloys
- 5Explain why most the metals we use are not elements.Elements are two soft and are too easily bent. If used they are usally mixed with other elements so they can sustain their shape.
- 6What us NOT a property of a substance?Cost or cheapness
- 7What is the word equation to get iron from iron oxideIron Oxide + Carbon = Iron + Carbon Dioxide
- 8Name 3 types of steel and give a important property for each oneLow Carbon Steel = Easily Shaped --- High Carbon Steel = Hard/ Solid --- Stainless Steel = Resistant to Corrosion
- 9Why are all steels AlloysSteel is a combination of Iron and Carbon
- 10Give 3 properties that make aluminium a useful metalLow Density --- Resistant to Corrosion --- Malleable ---
- 113 Reasons why titanium is expensiveElectrolysis is needed as high in reactivity series --- Titanium reacts with carbon making it brittle --- several stages are needed to extract from ore ---
- 123 reasons why we should recycle aluminium and titaniumTo prevent Environmental damage --- To make earth supply last longer --- It is more Sustainable and CHEAPER
- 13Name Three Methods used to extract a metal form a oreSmelting --- Electrolysis --- Reduction ---
