metals
 Metals are found on the _____________ of the periodic table.
 There are __________ metals than non-metals
 Common properties of metals include:
 Malleable: this means they can be bent and bashed into shape
 Ductile: this means they can be drawn out into thin wires
 Conductors: this means they allow heat and electricity to travel
along them
 Shiney: they are reflective of light
 Usually grey: most metals are a grey colour
 Solid at room temperature: except mercury (liquid)
Non-metals
 Common properties of non-metals include:
 Brittle: this means they break easily if hit
 Various colours: non-metals come in many colours
 Insulators: most non-metals are non-conductors, an
exception is graphite (C), it is an excellent conductor of
electricity.
 Solids, liquids and gases: non-metals come in all
different states. Bromine (Br) is the only naturally
occurring liquid non-metal.

solid: ___
2 after reading the descriptions below, decide if they are a metal or nonmetal
A. a shiny, silvery solid which is brittle and does not conduct heat or
electricity
B. A soft, malleable grey substance, shiny when freshly cut. It conducts
heat and electricity and has a low melting point.
C. Shiny, conducts electricity when solid, brittle, very high melting
point.
D. A shiny, silvery liquid, conducts heat and electricity well. Malleable
when solid
E. Soft, malleable substance, low melting point. Doesn’t conduct heat or
electricity
