C3 ionic bonding, metallic bonding and structure

• What is ionic bonding?

  A type of chemical bond
• What is the structure of an ionic lattice?

  A regular arrangement of ions
• How does ionic bonding affect melting points?

  Ionic compounds have high melting points
• What are the properties of ionic compounds?

  High melting points and conductivity
• What is the role of delocalised electrons in conductivity?

  They allow charge to move freely
• What is a characteristic of metallic bonding?

  Presence of delocalised electrons
• What does malleability refer to in metals?

  The ability to be shaped or bent
• What are the key terms related to ionic and metallic bonding?

  • Ionic bonding
  • Metallic bonding
  • Ionic lattice
  • Conductivity
  • Electrostatic force of attraction
  • Delocalised electron
  • Malleable
• How does the presence of different sized atoms affect metallic structure?

  It disturbs the lattice, preventing sliding
• What is the effect of alloying on metal properties?

  Alloys make metals harder and stronger
• What is required to break the electrostatic forces in ionic compounds?

  Input of energy
• What is the significance of the model used to describe metallic bonding?

  It helps visualize the structure and properties
• What is a limitation of the metallic bonding model?

  It does not accurately depict metal structure
• What happens to the conductivity of metals when they are alloyed?

  Conductivity may decrease due to structure changes
• What is the formula for calculating melting points in ionic compounds?

  There is no specific formula
• How do ionic compounds conduct electricity in solution?

  They dissociate into ions that move freely
• What is the relationship between ionic charge and melting point?

  Higher charge leads to higher melting points
