BONDING

Question 1

Describe the melting point in metallic bonds.

Answer 1

• High melting points
• Strong metallic bonds
• Lots of energy needed to break bonds

Question 2

Describe the melting points in ionic bonds.

Answer 2

• High melting points
• Strong ionic bonds
• Lots of energy needed to break bonds

Question 3

Explain the electric conductivity in ionic bonding.

Answer 3

• Conduct when (l) or (aq)
• Ions are mobile and free to carry charge
• Can’t conduct when (s)
• Ions are fixed in a lattice and cannot move and carry charge

Question 4

Describe the solubility in ionic bonds.

Answer 4

• Soluble in polar water

- Ions dissociate

Question 5

Describe the electrical conductivity in metallic bonding.

Answer 5

• Good

- Delocalised electrons are mobile and free to carry charge

Question 6

Describe the solubility in metallic bonding.

Answer 6

• Insoluble

- Polar water cannot break the strong metallic bonds

Question 7

Describe the strength in metallic bonding.

Answer 7

• Ionic charge increases
• More Delocalised electrons
• Stronger attraction between positive metal ions and delocalised electrons
• More energy needed to break them
