Properties of metals

Question 1

Physical properties

Answer 1

• they are strong
• good conductors of heat and electricity because of metallic structure in which the delocalised electrons act as charge carriers
• they are ductile
• they are sonorous
• they are maleable
• they are shiny when polished or freshly cut
• generally have high melting and boiling points
• high densities

Question 2

chemical properties include:

Answer 2

• may react with water, acids or oxygen
• lose electrons to form cations (oxidation process) when they react
• act as reducing agents
• cations that formed become oxidants
• a more reactive metal can displace an ion of a less reactive metal e.g Cu+²(aq) + Zn(s) → Zn+²(aq) + Cu(s)
