Metallic Character
Characteristics
Alkali Metals
Properties:
highly reactive
have low melting and boiling points
very soft ad can be cut easily
low densities (lithium, sodium, and potassium can float on water)
react very quickly with water
their hydroxides and oxides dissolve in water to form alkaline solutions
