Non reactive

All gases

all exist as single atoms

Highly reactive

Low melting point

Non-metallic

Form -1 ions

Do not form ions

Used in lighting

highly toxic

Shiny metals

soft and easily cut

highly reactive in water

Conducts electricity

Form 1+ ions

Typically Less reactive than other metals

Form coloured salts

Can form differently charged ions

Organize these properties into the right categories

Group 1 Metals

Group 7

Group 8

Transition metals

Dropdown

Group 1 metals become

reactive as we go down the group. This is because the

increases down the group- meaning the

are further from the positive attraction of the
