Well the sodium metal races round the water as the particles that are being let lose are moving the sodium around
What Happens When Sodium Metal Was Placed Into Water?
Explode
Sodium is most reactive element. When you placed in the water it will explode.
What happens is that the sodium metal touches the water and make the particles inside the water run wild and makes the sodium bounce around of the sides and it then sometime catch on fire. Too much sodium can make an explosion so be careful!!
