Questions from this subtopic
Each one with the model answer underneath.
- 1
Why do most metals have high melting points?
Model answer
They have giant structures held together by strong metallic bonds, which need a great deal of energy to overcome.
- 2
Describe the structure and bonding of a metal.
Model answer
A giant structure of atoms held together by strong metallic bonding.
- 3
Are the boiling points of most metals high or low?
Model answer
High.
- 4
How are the atoms arranged in a pure metal?
Model answer
In regular layers.
- 5
Why can a pure metal be bent and shaped?
Model answer
Its layers of atoms can slide over one another.
- 6
Why are pure metals unsuitable for many uses?
Model answer
They are too soft.
