- Properties of group 1 elements include1234:
- Softness
- Low melting points
- Reactivity increases down the group
- React with water to produce an alkaline metal hydroxide solution and hydrogen
- Must be stored under oil to keep air and water away from them
- Form metal hydroxides which are alkaline (with a pH above 7), which is why they are called alkali metals.

They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.www.bbc.co.uk/bitesize/guides/z3773k7/revision/1The group 1 elements are placed on the left of the periodic table. They are called the alkali metals because they are metals, and their oxides and hydroxides form alkaline solutions. In general, the alkali metals: are soft, and easily cut with a knife have relatively low melting points compared to other metals.www.creative-chemistry.org.uk/gcse/inorganic/group1All the Group 1 elements are very reactive They must be stored under oil to keep air and water away from them. When they react with water, Group 1 elements form metal hydroxides which are alkaline (with a pH above 7).
