A metal oxide together with oxygen gas

A metal chloride together with water

Just the metal and hydrogen gas

Metal hydroxide and hydrogen

The outer electron is further from the nucleus and lost more easily

The outer electron is held much closer to the nucleus down the group

The atoms gain extra electrons far more easily down the group

There are more outer-shell electrons to lose down the group

They get lighter in colour and their reactivity steadily increases down the group

They get darker, boiling point increases and reactivity decreases

They gradually become more and more reactive metals

Their melting and boiling points steadily decrease

They lose one electron to form a 1+ ion

They share electrons to form metals

They gain one electron to form a 1- ion

They do not react with metals

The atoms lose their outer electrons far more easily as you go further down the group

The atoms get steadily smaller and more compact as you go down the group

There are fewer outer-shell electrons in the atoms down the group

An electron is gained less easily as the outer shell moves further from the nucleus

Chlorine displaces bromine, turning the solution orange

Nothing happens at all and there is no reaction

Bromine displaces the chlorine from the solution

A grey solid precipitate of potassium metal forms in the solution

Yes, because iodine is more reactive than chlorine

No, iodine is less reactive than chlorine

Yes, because all of the halogens displace each other

Only if the solution is strongly heated

They each have just one electron in the outer shell

They are all reactive metals

They have a full outer shell of electrons

They have no electrons in them at all

As diatomic molecules of two atoms

As giant covalent lattices

As charged ions

As single atoms (monatomic)

Both increase

Both decrease

Boiling point increases, density decreases

They stay the same

It reacts with the metal filament to help it produce light

It is inert, so it does not react with the hot filament

It is highly flammable and burns brightly

It has a very high density compared with air
