Strong Bonding: Metallic

Question 0

Properties (metal):

- electrical conductivity

Answer 0

High

- freely moving electrons transfer electrical field

Question 1

What is metallic bonding?

Answer 1

Between 2 metal elements formed by freely moving and delocalised electrons and positive ions in a lattice. Electrons are not bonded to a single positive ions, hence the bonds are NON-DIRECTIONAL

Question 2

Properties (metal):

- thermal conductivity

Answer 2

High

- freely moving electrons transfer Ek through lattice

Question 3

Properties (metal):

- malleability/ductility

Answer 3

Delocalised electrons have the ability to move in between shifter positive ions, keeping the structure together and ensuring that the electrostatic attractions are maximised

Question 4

Properties (metal):

- melting/boiling point

Answer 4

High
- the more strongly bonded the positive ions are to the lattice by ELECTROSTATIC FORCES OF ATTRACTION with the mobile electrons, the higher the temperature at which a metal melts (strongly bonded)

Question 5

Properties (metal):

- hardness

Answer 5

Really strong bonds, hence a lot of energy is required to disrupt it
