As you go down the metals become more reactive
the outer electron is more easily lost as it is further from the nucleus
They have lower melting and boiling points
Lithium, Sodium, Potassium, Rubidium and Caesium
all have one outer electron
form ionic compounds with non-metals
Keen to loose their outer electron and become 1+
produce white compounds that dissolve in water to form colourless solutions
React with water to produce hydrogen gas
They float and move around the surface, fizzing vigorously
They form hydroxides that dissolve in water to give alkaline solutions
