1
Q
describe the monatomic structure and its attraction
A
- individual atoms ➡️ not joined
- weak forces between atoms
- no bond
2
Q
describe simple molecular structure and its attraction
A
- individual molecules ➡️ not joined ➡️ inside joined by covalent bonds
- weak forces between molecules
3
Q
describe giant covalent structure and its attraction
A
- giant structure ➡️ joined by covalent bonds
4
Q
describe ionic structure and it attraction
A
- giant structure of positive and negative ions ➡️ strong attraction between ions
5
Q
describe metallic structure and its attraction
A
- giant structure of positive metal ions ➡️ surrounded by electrons
- strong attraction between positive ions an delocalised electrons
