15
Q

Explain the trend in reactivity in group 1?

A

Nuclear attraction decreases down the group so it becomes easier to lose the outer shell electron.

Q

Describe the structures formed by group 7 elements?

A

They exist as diatomic molecules, they are simple molecular substances.

17
Q

Describe the trend in reactivity in group 7?

A

Reactivity decreases down the group.

18
Q

Explain the trend in reactivity for group 7?

A

Group 7 elements want to gain electrons, this becomes harder as the atoms get larger.

19
Q

What is a displacement reaction?

A

A reaction where a more reactive halogen takes the place of a less reactive halogen in a compound or solution.

20
Q

Where are transition metals on the periodic table?

A

The central block of the periodic table.

21
Q

How are their compounds different to group 1 metals?

A

They can form coloured compounds.

22
Q

What are the charges on their ions?

A

Transition metals can form ions with different charges e.g. Fe2+ & Fe3+.

23
Q

How do their properties compare to group 1 metals?

A

They are less reactive, harder and denser than group 1 metals.
