What is metallic bonding
Attraction between delocalised electrons and positive ions arranged in a lattice
What makes for a stronger metallic bond?
The stronger the attraction between nucleus of meta atom and the delocalised electrons the stronger the metallic bonding
What is smaller rubidium atoms or potassium atoms
Potassium
What will have a greater metallic bond - potassium or aluminium
Aluminium
Smaller and higher charge
Describe the structure of metallic bonding
Lattice structure of metal atoms where the outer shell electrons from each atom are delocalised
What are the 4 properties of metallic bonding?
High m.p and b.p
Conducts electricity
Strong
Insoluble
What makes metallic bonding strong
Layers can slide over each other while maintaining a metallic bond
Why is metallic bonding insoluble
The energy released by the solvent is less than the energy needed to break the bonds
