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 and hard and dense.
Ductile
Can be drawn out into wire.
Malleable
Can be hammered into different shapes.
Alloy
Is a mixture of metals.
Corrosion
It 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…
Iron (Fe)
Rust provention
Galvanising, painting and greasing.
Galvanising
Coating with zinc.
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.

…hydrogen gas is given off.
Zinc reacts with hydrochloric acid to form…
…zinc chloride and hydrogen.
