What does a metallically bonded ion look like?
It has clear, ordered rows of metal ions, surrounded by a sea of delocalised electrons.
What is metallic bonding in terms of electrostatic attractions?
The strong attraction between positive metal ions and a sea of delocalised electrons.
What are some typical physical properties of metals (4 things)? Why?
High melting point and boiling point Strong metallic bonds are present, which require lots of energy to overcome and break the bonds. Conductor of electricity A sea of delocalised electrons can move and carry current through the metal Conductor of heat Energy is transferred by the delocalised electron Malleable and ductile Layers can slide while maintaining metallic bonding
