The alkali metals, halogens and noble gases are three important groups in the periodic table. The alkali metals are soft, reactive metals. They react vigorously with water and become more reactive as you go down the group.The halogens are reactive non-metals.They become darker as you go down the group.he alkali metals have the following properties in common: 1  they have low melting and boiling points compared to most other metals. 2  they are very soft and can be cut easily with a knife. 3  they have low densities (lithium, sodium and potassium will float on water).
