What are the typical products of metals?
They conduct electricity well and they're malleable.
1 of 24
What are the properties of transition metals?
They have high melting points. They form colourful compounds, eg. potassium chromate is yellow.
2 of 24
How does the structure of a metal allow it to conduct electricity?
The ability of electrons to move freely through the structure makes metal good conductors of electricity.
3 of 24
What arrangement do metals have?
Metals consist of a regular arrangement of atoms held together with metallic bonds.
4 of 24
What does the metallic bond give the metal?
The metallic bonds give the metal a giant structure consisting of positive ions and free electrons, because metallic bonds allow the outer electrons of each atom to become delocalised.
5 of 24
What does the giant metallic structure and strong bonds give the metal?
The giant metallic structure and strong bonds mean that metals have extremely high melting points and are insoluble.
6 of 24
What happens when the layers of atoms slide over each other?
The metals can be bent and shaped. This makes metals malleable.
7 of 24
What are the two properties of alkali metals?
They are soft and have low melting points.
8 of 24
What happens as you go down group 1?
The elements in group 1 get more reactive as the atomic number increases.
9 of 24
What happens when lithium, sodium or potassium are put in water?
They react vigorously to form hydroxides.
10 of 24
What happens when an alkali metal reacts water?
Hydrogen is produced.
11 of 24
Test for hydrogen
A lighted splint will indicate the hydrogen by making the 'squeaky pop' as the hydrogen ignites.
12 of 24
What are group 7 elements known as?
Halogens
13 of 24
What are the states of halogens at room temperature?
Chlorine: a fairly reactive, poisonous, dense green gas. Bromine: a dense, poisonous, orange liquid. Iodine: a dark grey crystalline solid.
14 of 24
What happens when halogens react with metals?
To form metal halides.
15 of 24
Why is an element more reactive the higher up group 7 it is?
Because the outer shell is nearer to the nucleus, so the pull from the positive nucleus is greater which attracts extra electrons more strongly.
16 of 24
What happens when halides dissolve in water?
The halide ions are free to react
17 of 24
Displacement reaction
If a more reactive halogen reacts with a solution contain halide ions it will displace the less reactive halogen.
18 of 24
Group 0
The noble gases. All colourless gases at room temperature.
19 of 24
Why are noble gases inert?
Because they have a full outer shell. They don't need to lose or gain electrons.
20 of 24
Properties of noble gases
Colourless gases at room temp. Inert. Non-flammable.
21 of 24
Helium
Low density so is used in airships and party balloons.
22 of 24
Argon
Used to provide an inert atmosphere in filament lamps.
23 of 24
What happens to the boiling points and densities of the noble gases as you go down the group?
They increase.
