Metallic Bonding

Question 1

metallic bonding

Answer 1

• metals have a giant structure of positive ions surrounded by a sea of delocalised electrons
• the electrostatic attractions between the positive ions and electrons = metallic bonding = gives metals their properties

Question 2

metals properties

Answer 2

1. good conductors of electricity and heat
   - delocalised electrons are able to move through the structure = conduct electricity = energy can be transferred quickly so conducts heat well
2. malleable
   - layers of ions in a metal can slide over each other making metals malleable = they can be hammered or rolled into flat sheets

Question 3

electric current =

Answer 3

flow of electrons or ions
