The three alkalis that float on water are Lithium, Sodium and Potassium.
This is because they are much denser that water.
As shown this is the density of each substance.
0.534 - Li
0.968 - Na
0.890 - K
1.000 - Water

The word equation for the reaction of alkali metals with water?
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
How can water float on water?
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).

Why ice floats in in water?
