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 |
