Metallic bonding Flashcards
1
Q
What do metallic substances contain?
A
Delocalised electrons
2
Q
What is the structure of metallic substances?
A
Giant metallic lattice
3
Q
Why do metallic substances have high melting points?
A
- Positive metal ions in a sea of delocalised electrons
- Strong electrostatic forces between the metal ions and delocalised
electrons - Lots of energy required to overcome these forces
- High melting point

Q
Why do metallic substances conduct electricity?
A
Delocalised electrons can flow through the structure and carry charge
