Which statement best described the structure of a metal?
A lattice of positive metal atoms surrounded by delocalised electrons.
A lattice of positive metal ions surrounded by delocalised electrons.
A lattice of metal atoms in neat rows.
A lattice of metal ions.
Select three which are properties of metals.
Can conduct electricity and heat
Ductile
Low melting points
Flaky
Malleable
Metals are malleable, what does this mean?
They can be bent or dented
They can be pulled into long and thin wires
They heat up quickly
They can be taken apart
Metals are ductile, what does this mean?
They can be bent or dented
They can be pulled into long and thin wires
They heat up quickly
They can be taken apart
Metals are malleable because the metal ion are arrange in (a) which can slide over each other.
Metals can be pulled into long thin wires, when this happens the ions move closer together but they do not repel eachother because the delocalised electrons can move between the ions and s (a) them form each other.
