level questions: Metals and alloys
| Question | Answer |
|---|---|
| Structure of metals | giant structure of atoms arranged in regular layers |
| Electrons in metals | The electrons in the outer energy levels are delocalised |
| Attraction in metals | Strong electrostatic attraction between metal ion and sea of negative delocalized electrons |
| What do scientist call the electrostatic bonds in metals | Metallic bond |
| Properties of metals | - High melting and boiling point because great energy is required to break metallic bonds - Good conducters of heat and electricity |
| Why can metals be bent and shaped | The layers of atoms are able to slide over each other |
| How do we make metals harder | alloys |
| What do alloys mean in terms of properties for metals | The different size of atoms makes it harder for them to slide over each other |
| Which is harder pure metals or alloys | Alloys |
