25
Why does sodium float on water?
It is less dense than water
26
What gas is given off when Group 1 metals react with water?
Hydrogen
27
What are the Group 1 elements also known as?
Alkali metals
28
Why are they known as this?
The react with water to produce an alkaline solution
29
Describe the trend in reactivity as you go down Group 1.
Increases
30
Why do the elements in Group 1 share similar properties?
They all have one electron in their outer shell
31
Why do alkali metals form +1 ions?
They lose one electron from their outer shell
32
What are Group 7 elements also known as?
Halogens
33
What is a diatomic molecule?
A molecule containing 2 atoms
34
What is the charge on a halide ion?
-1
35
What sort of compounds do halogens form with other non-metals?
Molecular compounds which are gases or liquids
36
What is the difference between a halide and a halogen?
Halide is a -1 ion, Halogen is a neutral atom
37
Describe the trend in reactivity down Group 7.
Decreases
38
Why do the elements of Group 7 get less reactive down the group?
The outer shell is further from the nucleus, becomes harder to attract an extra electron for a full outer shell
39
Why will iodine not displace bromine from magnesium bromide?
Iodine is less reactive than bromine
40
What gas is given off when lithium reacts with water?
Hydrogen
41
Name 3 noble gases.
