Metallic Bonding & Structure

Question 1

Describe the structure and bonding of metallic compounds

Answer 1

C - giant metallic lattice
B - many strong metallic bonds
D - strong electrostatic force of attraction between cations and delocalised electrons

Question 2

Explain why metals are described as malleable.

Answer 2

Cations can slide over each other so can change shape while the metallic bond remains in place

Question 3

Describe and explain the electrical conductivity of metals.

Answer 3

Can conduct in solid or liquid states.
—> delocalised electrons are free to move and carry a charge through the structure

Question 4

Describe and explain the melting and boiling points of metallic compounds.

Answer 4

High melting and boiling points.
—> lots of energy is required to overcome the strong electrostatic force of attraction between cations and delocalised electrons

Question 5

Describe and explain the solubility of metals.

Answer 5

Metals do not dissolve!
—> and interactions between metal and polar solvents would instead lead to reactions
