metallic bonding

• what does malleable mean ?

  metals bent and shaped without breaking
• metals form giant structures where electrons in the outer shell of metal atoms are free to move called delocalised electrons
• what is metallic bonding ?

  force of attraction between delocalised electrons and positive metal ions
• metallic bonds are strong so metals can maintain a regular structure and usually have high melting and boiling points
• metals are good conductors of electricity and heat because the delocalised electrons can move throughout the metals
• due to ions sliding over each other most metals are ductile
• what does ductile mean ?

  they can be drawn / pulled into wires making them suitable for electric cables
