1. Metallic Bonding

Question 1

What is a metallic bond?

Answer 1

The strong electrostatic forces of attraction between the positive metal ions and the sea of delocalised electrons.

Question 2

Why do metals have high melting and boiling points?

Answer 2

• It has a giant lattice structure
• There are strong electrostatic forces of attraction between the positive metal ions and the negative delocalised electrons within the metal lattice structure
• These require lots of energy to be broken

Question 3

Why can metals conduct electricity?

Answer 3

There are delocalised electrons available to move and carry charge through the structure.

Question 4

Why are metals malleable?

Answer 4

This is because the atoms/ions are arranged in layers which can slide over each other when a force is applied.

Question 5

Structure of Metals

Answer 5

• Positive Ions
• Arranged in layers
• A sea of delocalised electrons
