If you drop sodium metal into water, two reactions happen:
first 2Na + H2O -> 2NaOH + H2
then 2H2 + O2 -> 2H2O
The second reaction causes the huge explosion that makes this either an "exciting" experiment (if you drop the sodium into water from thirty or forty feet up) or a dangerous one (if you do it in the classroom).
Because the positive ions mix together to make them unstable
For example the reaction with water.
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Hydrogen can by generated, for example, from the reaction between alkali metals and water.
For example hydrogen is released when alkali metals react with water.
alkali metals react violently in cold water
The solubility of alkali metals in water is high. Alkali metals such as lithium, sodium, and potassium readily dissolve in water to form alkaline solutions.

They contain similar properties. For example, in the first colum of the periodic table all contain alkali metals. Alkali metals react with water.
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
the alkali metals bases reacts with the acids to form salt and water example NaOH+HCl=H2O+NaCl
Hydrogen can by generated, for example, from the reaction between alkali metals and water.
