level questions: Chemical bonding
| Question | Answer |
|---|---|
| What are the 3 ways atoms can bond | Ionic metallic and covalent |
| What do Ionic bonding involve | Attraction between oppositely charged ions |
| Where are ionic bonds found | compounds made of metals and non metals |
| What do Covalent bonding involve | Two atoms sharing an electron |
| Where are covalent bonds found | Non metals |
| What do Metallic bonding involve | Attraction between positive charged ions and negatively charged delocalised electrons |
| Where are metallic bonds found | In metals and alloys |
| What are positive ions also known as | cations |
| What are negative ions also known as | anions |
| What happens when an atom forms an ion | They try to fill up or empty their outer shell |
| How do ionic bonds form | One atom transfer an electron to another so that both atoms form oppositely charged ions which are then attracted to each other by electrostatic forces |
| What are ions | charged particles that form when an atom losses or gains electrons |
