Properties of metals and non-metalsProperties of metals and non-metals
Metals have very high melting points (which means that they are
usually _____) whereas non-metals will melt at lower ___________
All metals conduct heat and __________ very well, whereas non-
metals don’t (usually)
Metals are strong and ______ but bendable. Non-metals are usually
_____ or they will snap.
Metals will _____ when freshly cut or scratched, whereas non-metals
are usually dull
Metals have higher _______ than non-metals (i.e. they weigh more)
Metals can be used to make ______ (a mixture of different metals)
Words - alloys, electricity, solids, weak, densities,

Reactions of metals with oxygenReactions of metals with oxygen
When a metal reacts with oxygen it will form a METAL
OXIDE. This is what happens when a metal rusts or burns.
METAL + OXYGEN METAL OXIDE
Copy and complete the following reactions:
1) Magnesium + oxygen
2) Copper + oxygen
3) Calcium + oxygen
4) Iron + oxygen

Reactions of metals with waterReactions of metals with water
When a metal reacts with water hydrogen is always given off.
The other product will be either a metal hydroxide or a metal
oxide.
Copy and complete the following reactions:
1) Sodium + water
