They react vigorously with water. Hydrogen gas is given off. The metal reacts with water to form an alkali - the hydroxide of the metal.

What is the balanced symbol equation for lithium and water?
2Li + 2H20 -> 2LiOH + H2
2 of 8
How can we predict the properties of rubidium and caesium?
By knowing the melting points, boiling points, appearance and conductivity of lithium, sodium and potassium.
3 of 8
Why are atoms of group 1 alkali metals similar?
Because they all have one electron in their outer shell
4 of 8
What is formed when atoms of alkali metals react?
A full outer shell, to create a stable electronic structure. An ion, which has one more positive charge in its nucleus than negative electrons in the shells, so it becomes a positive ion
5 of 8
What makes an alkali metal more reactive?
the easier it is for an atom to lose one electron
6 of 8
What is oxidation?
When electrons are lost.
7 of 8
What can a flame test find out?
If lithium, sodium or potassium is present in a compound.
