What is a metallic bond?
The strong electrostatic forces of attraction between the positive metal ions and the sea of delocalised electrons.
Why do metals have high melting and boiling points?
• 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
Why can metals conduct electricity?
There are delocalised electrons available to move and carry charge through the structure.
Why are metals malleable?
This is because the atoms/ions are arranged in layers which can slide over each other when a force is applied.
Structure of Metals
• Positive Ions • Arranged in layers • A sea of delocalised electrons
