Metallic bonding

Question 1

Give the characteristics/Properties of Metallic bonding, at least 4

Answer 1

Characteristics:

• electrons are delocalised = free to move between the ions (only the outer shell)
• no. of delocalised electron per ions matches the group no. –> higher the no. of the delocalised electron the stronger metallic bonds
• can carry electrical/thermal energy so thus good conductors for electricity/heat
• they are METAL IONS/METALLIC LATTICE not ATOMS

Properties:

• high melting points (not high as ionic’s electrostatic force
• rows of metal ions can slip through each other -> bent into different shapes = MALLEABLE)
• DUCTILE = drawn into wires
