Periodic Table

Question 1

Name 10 facts about metals

Answer 1

• usually solid (except for mercury, which is a liquid)
• melting and boiling points are usually high
• usually hard and dense
• good conductors of electricity
• good conductors of heat
• shape can be changed by hammering (are malleable)
• can be pulled out into wires (are ductile)
• grey in colour (except gold and copper)
• can be polished
• usually make a ringing sound when struck (are sonorous)

Question 2

Name 9 facts about non-metals

Answer 2

• solids or gas (except for bromine which is a liquid) at room temperature
• melting and boiling points are often low
• are softer than metals (except for diamond)
• poor conductors of electricity (except graphite, a form of carbon)
• poor thermal conductors
• most are brittle when solid
• vary in colour
• dull surface when solid
• not sonorous
