Before taking the test
- —Memorise the reactivity series: K, Na, Ca, Mg, Al, Zn, Fe, [H], Cu, Hg, Ag, Au, Pt
- —Know how metals react with water at different rates: Na/K (cold water) → Mg (hot water) → Fe (steam) → Cu (no reaction)
- —Understand extraction methods based on reactivity: electrolysis (top), carbon reduction (middle), heating (bottom)
- —Practice ionic bond formation with electron configurations for NaCl and MgCl₂
- —Remember alloy compositions: brass (Cu+Zn), bronze (Cu+Sn), stainless steel (Fe+Cr+Ni+C), solder (Pb+Sn)
- —Know exceptions: Hg is liquid, graphite conducts, Na/K are soft, Al₂O₃/ZnO are amphoteric
