group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.
Furthermore, what are the properties of the alkali metals?
The alkali metals have the following properties in common:
- they have low melting and boiling points compared to most other metals.
- they are very soft and can be cut easily with a knife.
- they have low densities (lithium, sodium and potassium will float on water)

How many alkali metals are there in the periodic table?
Alkali metal. Alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
