Metals Flashcards
What happens when a metal is hit
Layers of metal ions slide over each other -the bonds do not break because of the delocalised electrons.
Properties of metals name 12 in total 7 important ( listed first )
Conductors of heat / electricity Malleable Solid state at room temp (except mercury) Strong Dense Ductile (can be drawn into wires) High melting points
Sonerous Shiny Not brittle Delocalised electrons Found in earths crust
What kind of structure do metals have
Lattice
What is metallic bonding
Attraction between delocalised electrons and metal ions
What do delocalised electrons allow metal to do
Conduct heat / electricity
Have a higher melting point
Be bent
What does delocalised mean
Free can move
How does metallic bonding work
Metals are held together by electrostatic attraction between positive metal ions and negative delocalised electrons
metallic bonding memes metals
strong
High melting boiling point
Conductor
Why are metals strong and malleable
Layers slip easily over each other whilst keeping the strong attraction
Why does delocalised electrons mean good conductor
Electrons free to move carry energy with them
