Question 14

How are the particles in a metal held together?

Answer 14

Metallic bonds

Question 15

Why do metals have high melting points?

Answer 15

Because it takes a lot of energy to seperate the metallic bonds

Question 16

What are solid metals called?

Answer 16

Crystalline

Question 17

What does crystalline mean?

Answer 17

That the particles are close together and in a regular arrangement.

Question 18

Do metals have electrons?

Answer 18

Yes, they have loose electrons on the outer shells which form a ‘sea’.

What are all metals?

Answer 19

Malleable, meaning they can be hammered into shape

Question 20

Why is malleability an advantage for metals?

Answer 20

They have more uses for it. E.g. Jewellery
