Metallic Structures

Question 1

Metals consist of a [ ] structure

Answer 1

Giant

Question 2

What causes metal’s properties?

Answer 2

Their sea of free electrons

Question 3

Where do the delocalised electrons come from?

Answer 3

The outer shell of every metal atom in the structure

Question 4

Why are metals good conductors?

Answer 4

The free electrons are free to move through the whole structure so they conduct heat and electricity

Question 5

What do the free electrons also do (except make the metals conductive)?

Answer 5

They hold the atoms together in a regular structure

Question 6

There are also strong forces of [ ] between the [ ] and the negative electrons

Answer 6

electrostatic attraction

positive metal ions

Question 7

Why can metals be bent and shaped?

Answer 7

The free electrons allow the layers of atom to slide over each other

Question 8

Are alloys stronger or weaker than metals?

Answer 8

stronger

Question 9

What is an alloy?

Answer 9

A mixture of two or more metals

Question 10

Why are alloys stronger?

Answer 10

Different elements have different sized atoms. So when another metal is mixed with pure metal, the new metal atoms will distort the layers of metal atoms, making it more difficult for them to slide over each other. So alloys are harder
