Patterns of Reactivity

Properties 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
dont (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, temperatures, tough, shine

Reactions 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.
4
Reactions 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.
