Metalic bonding Flashcards
What does metallic bonding involve?
Delocalised electrons.
What kind of forces are they?
Strong electrostatic forces of attraction.
What are the forces between?
positive metal ions and shared negative electrons.
What is the purpose of the forces?
To hold the atoms together.
What produces the properties of metals?
Delocalised electrons.
What is the state of a metal at room temperature?
Solid.
What kind of forces are they?
Very strong.
How can the forces be broken?
Lots of energy.
What is the boiling point of metallic bonding?
very high.
What do they conduct?
Electricity and heat.
Why are they malleable?
Layers of atoms can slide over each other.
What is harder pure metals of alloys?
Alloys, when mixed with another metal it distorts the layers which makes it difficult to slide over each other.
