6. Metallic Bonding Flashcards
1
Q
Which structure is shown here?
A
A metallic lattice
2
Q
What is metallic bonding?
A
The attraction between positive ions and (a sea of) delocalised electrons
3
Q
Which electrons in metals are delocalised?
A
The outer (valence) electrons
4
Q
What does “delocalised” mean?
A
Not attached to any one atom.
Free to move around lattice
5
Q
Why do metals conduct electricity in liquid and solid state?
