Transcript Metal vs non-metal
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.
Problems:
1 Are there more metals or non-metals?

Answer each one as you go, we will do this as a class by
looking up the information together
1. What are the physical properties of metals?
2. Which elements are considered to have both metal and
non-metal properties? these are also known as semi-metals.
3. What are some of the chemical properties/reactions of
metals (list at least 3 different reactions)?
4. Type in the word non-metals: What are some of the
properties of non-metals?
Stick in worksheet and complete it.
Finish off the other worksheet you were given at the
end of last term.
Yellow book: pg pg 20-21
No yellow book: copy and complete the following
problems.
1 complete the sentences below using these words: lustre, ductile, state,
malleable, brittle

C. a material which shatters or snaps easily is: ___
D. a material which can be pulled into a wire is : ___
E. at room temperature, all metals except for Hg (_________) are in the
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
