Q
What are the electrons in metals like?
A
They are de localised electrons
1
Q
What are the properties of metals?
A
Good conductors of heat
Good conductors of electricity
Are able to be bent and shaped
High melting points
2
Q
What is the structure of metals?
A
Free electrons around positive fixed ions.
3
Q
Why are metals good conductors of electricity and heat?
A
Delocalised electrons move quickly and pass on the energy quicker
4
Q
Why dob metals have high melting points?
A
Because there are strong forces of electrostatic attraction
5
Q
Why are metals allowed to be bent and shaped?
A
The layers can slide over each other.
6
Q
Why are alloys harder than metals?
A
They have different sized atoms meaning layers do not slide over each other as well.
