Metals
Reactants
metals and acids
Metals that react with water react quickly with acids and some metals that don't react with water react with acids.metal + acid [arrow] salt + hydrogen
-
O2
corrosion is where metals react with oxygen, that makes them weaker and when iron reacts with oxygen it rusts.metal + oxygen → metal oxide
Metals vs non metals
Metals: shiny, conductive, high melting points,solid,malleable.
Non Metals: dull,poor conductor, low melting points, solid or gas, can't bend without breaking.
catalysts
Speeds up the reaction of some metal reactions. e.g. platinum is a catalyst in car catalytic converters.

alloys
an alloy is a mixture of a metal and a chemical to make a more useful non pure metal (element) e.g. steel is an alloy of iron; steel is stronger than iron and doesn't rust.
