4. Metals
• Shiny lustre
• Malleable
• Ductile
• Solid at room
temperature
(except Mercury)
• Good conductors
• Mostly silver or
grey
Non-metals
• Dull / not shiny
• Brittle – can shatter
or be crushed
• Are solids and
gases except
Bromine
• Not malleable or
ductile
• Powdery solids
• Low melting point
• Poor conductors /
good insulators
Metalloids
•Share properties of
metals and non-metals
•Can be shiny or dull
•Can be malleable or
ductile
•All solids at room
temperature
•Semiconductors
•Poor conductors of
heat
