Metals And Non-metals Flashcards
Sonorous
If you hit it it makes a sound
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
An undesirable process whereby a metal changes to its oxide or some other compound by combining with oxygen from the air
Rusting
The corrosion of iron(Fe)
Rust prevention
Galvanising, painting, greasing
Galvanising
Coating with zinc
Activity series
All metals have similar properties but do not react at the same rate
The activity or reactivity series is like a league table for metals
A good way to compare metals is to see how they react with water and acid
Word for activity series
Zinc+Hydrochloric acid–> Zinc chloride + hydrogen
Reactivity
Calcium(cats)
Magnesium(makes)
Zinc(zebras)
Copper(cry)
Metals react with acid
Hydrogen gas is given off
Zinc reacts to hydrochloric acid to form
Zinc chloride and hydrogen
