Metallic Bonding Flashcards
1
Q
Different properties of diamond and graphite
A
Hardness:
Diamond is hard the strong colevent bonding throughout make it different to stretch surface of the crystals
Graphite is sort the force between the layers of graphite are weak.
2
Q
What is metallic bonding
A
The atom are packed closely together and regular arranged in layers.
The metal bond is formed when by attractive force between the layer of electrons and positive ions.
The lattice is formed when metal lattice tends to loses their outer electrons and positive ions.
3
Q
What are strength of metal bonds increase
A
The positive charge op ions increase
The size of metal irons increase.
The number of localized electrons increases
