Metallic bonding

Question 1

Metallic bonding

Answer 1

consisted of positive ions with electrons moving around and between them as sea of delocalised negative charge- strong forces

Question 2

Properties of metals

Answer 2

• high melting and boiling points - strong electrostatic attractions
• good conductors of heat - delocalised electrons can transfer kinetic energy
• good electric conductors - delocalised electrons are mobile and can carry charge
• insoluble - too strong to break
• malleable and ductile - ion layers can slide when hit with a hammer and still retain an attraction between ions and delocalised electrons
