Lessons in this topic
- 0 Start here A roadmap: two kinds of element, the reactivity list, and its uses. · 4 min You are here
- 1 Two kinds of element Simple tests sort most elements. A few famous exceptions break the pattern. · 6 min
- 2 What an oxide tells An oxide reacts with an acid, a base, both or neither. That shows its kind. · 6 min
- 3 With air, water and acid Each metal reacts with air, water and acid in its own way. · 9 min
- 4 Who pushes whom out A displacement reaction shows which of two metals is more reactive. · 8 min
- 5 The reactivity series Displacement results line the metals up in order of reactivity. · 8 min
- 6 Compounds that carry charge Dissolved salts conduct, because their particles carry charge. · 7 min
- 7 Getting a metal out Metals come from ores. A metal’s place in the series decides how it is got out. · 8 min
- 8 Rust and what stops it Rust needs air and water together. A zinc coat protects iron. · 8 min
- 9 Mixed on purpose An alloy mixes a metal with other metals or a non-metal. · 7 min
- 10 Purifying copper Electrolysis makes impure copper pure. The impure bar is the anode. · 8 min
- 11 Checkpoint: metals at work Six marked questions on metals, the series and refining. · 6 min
- 12 The big picture One ordered list helps explain reactions, extraction, rust and alloys. · 4 min
- 13 Track quiz The ten rules from the lessons, then fourteen short questions. · 8 min
