C2.2.8 - Structure of Metalsl Flashcards
1
Q
What are all metals at room temperature?
A
Solid (apart from mercury)
2
Q
Delocalised electrons
A
Electrons leaving metals when they react, to form a sea, around positive ions
3
Q
Define metallic bonds
A
Strong electrostatic forces (attraction) between delocalised electrons & close packed (positive) metal ions
4
Q
1 advantage and 1 disadvantage of: Dot and cross diagrams
A
- Shows how atoms bond and the electrons
- Doesn’t show the 3D arrangement of molecules
5
Q
1 advantage and 1 disadvantage of: Ball and stick model
A
- Shows how atoms bonded and is 3D
- Doesn’t show electrons or chemical symbols
6
Q
1 advantage and 1 disadvantage of: 2D and 3D Models
A
- 2D doesn’t have a 3D arrangement
- 3D doesn’t show bonds or electrons
7
Q
What do ALL diagrams and models not show?
A
Intermolecular forces
