Metals and non Metals Flashcards
Sonorous
If you hit it,it makes a noise
Properties of metals
Electrical conductors,heat conductors,shiny,sonorous,ductile,malleable,high melting point,hard and dense
Ductile
Can be drawn out into wire
Malleable
Can be hammered into different shapes
Alloy
Is a mixture of metals
Corrosion
Is an undesirable process whereby a metal changes to its oxide or some other compound by combining with oxygen from the air
Rusting
Is the corrosion of FE(iron)
Rust prevention
Galvanising painting greasing
Galvanising
Coating with zinc
The activity series
All metals have similar properties but do not react at the same rate
A good way to compare metals is to see how they react with water and acid
Reactivity
Calcium,magnesium,zinc,copper
Cats make zebras cry
When metals react to an acid
Hydrogen gas is given off
Zinc reacts with hydrochloric acid to form
Zinc chloride and hydrogen
