1
Q
Properties of group 1 metals
A
Soft, low density
2
Q
Reactivity of group 1 metals
A
Reacts with air to form metal oxide, reacts with water to form an alkaline solution of metal hydroxide and hydrogen gas, reactions down the group are more rapid
3
Q
Fluorine at room temperature
A
Pale-yellow gas
4
Q
Chlorine at room temperature
A
Green gas
5
Q
Bromine at room temperature
A
Reddish-brown liquid
6
Q
Iodine at room temperature
A
Grey solid
7
Q
Why are elements further down the group in metals more reactive?
A
More outer shells, electrons can be donated more easily due to weaker bonds
8
Q
Why are elements further up the group in non-metals more reactive?
A
Fewer outer shells, electrons can be accepted more easily due to stronger bonds
