|
What happens when a metal atoms bond with other metal atoms? |
Metals lose their outer shell electrons forming positive ions |
|
|
How do you describe metallic bonding in a metal? |
metallic bonding in a metal: Regular arrangement of positive ions in a sea of delocalised electrons |
|
|
What structure do metals form? |
metals form Giant metallic lattices |
|
|
What is a metallic bond? |
Metallic bond: V. strong attraction between negative delocalised electrons and positive ions |
|
|
Which particles are fixed and which can move in a metal ion? |
Fixed : positive ions (lattice) Moving : Delocalised electrons |
|
|
Why do metals have High mp + bp? |
High mp + bp: Require large amount of energy to break V.strong metallic bonds (attraction between positive ions and delocalised electrons) |
|
|
How does charge affect the attraction? |
Greater charge = Greater attraction (between positive ions and delocalised electrons) |
|
|
Why are metals good electrical conductors? |
Good electrical conductivity: Delocalised electrons can move |
|
|
Why are metals Malleable and Ductile? |
Malleable + Ductile: Layers of positive ions can slide over each other |
