    - potassium and sodium belong to the same group, they are very reactive metals which react with water to form a silvery ball and dissolve quickly

    - no.1-5 dissolves in water to form alkaline solution

    - sliver and gold are not very reactive

    - reactive metals form oxides readily when they are exposed to air e.g. iron form Fe2O3 (rusting)
