The reactivity series

• Copper is a moderately reactive metal that does not react with water but can react with acids.
• In metal displacement reactions, a more reactive metal can replace a less reactive metal from its compound.
• Potassium is a highly reactive metal that reacts vigorously with water.
• Gold is a noble metal that is unreactive and does not easily corrode.
• Silver is a very unreactive metal that does not react with most substances, including air or water.
• The reactivity series shows the relative ability of metals to displace other metals from their compounds when they are placed in a solution containing those metals.
• The reactivity series shows the relative reactivity of metals when they are exposed to oxygen or water.
• Metal A will displace Metal B from its salt solution if it is more reactive than Metal B.
• When two metals are placed together in an electrolyte (a substance that conducts electricity), the more reactive metal will be oxidized while the less reactive metal will be reduced.
• Sodium is also a highly reactive metal that reacts violently with water.
• Lithium is another highly reactive metal that reacts explosively with water.
• Iron is a relatively reactive metal that rusts when exposed to oxygen and moisture.
• When two different metals are put into an acidic solution at the same time, the one lower down on the reactivity series will be oxidized by the one above it.
• A reaction between two elements occurs only if both elements have sufficient energy to overcome the activation energy barrier.
• Metal A will displace Metal B from its salt if it is more reactive than Metal B.
• If both metals form bubbles at the same time, then they have equal reactivity.
• Potassium, rubidium, cesium, francium, and caesium are all highly reactive metals that react vigorously with water.
• Sodium is an alkali metal that is highly reactive and forms sodium hydroxide when exposed to water.
• Magnesium is even less reactive than lithium and forms a white coating when exposed to air.
• metal + water -> metal hydroxide + hydrogen
• a native metal is a metal that is very unreactive and found in the earths crust
• annodes are positive, cathodes are negative
• non-metal ions move towards the annode (positive), and metal ions move towards the cathode(negative)
• an ore is a rock that contains enough of a metal to be economically extracted
• bauxite is an ore that contains aluminium oxide
• as you go down group 1, the reactivity increases
• zinc, iron, tin and lead can be extracted using carbon
• potassium, sodium, calcium, magnesium and aluminium can be extracted using electrolysis
• an electrolyte is the compound you want to split up using electrolysis
• molten is a substance in a liquid state (usually because it has melted)
• alkali metals are so reactive that they have to be stored in oil
• you can determine whether a metal is worth extracting based on how much metal is in the ore, and how much it is worth
• you can test if hydrogen has been produced from the squeaky pop test
• ferrous metals are any metal that contain iron
