Sodium burns with a golden yellow flame when it is heated.Sodium metal is lighter than water, hence it floats on water.
Sodium metal is silver white in color when it is freshly cut, but it suddenly forms an oxide layer if kept open in air. Sodium is a soft metal and it can be cut even by using a kitchen knife. Here are the interesting facts about Sodium element. That means sodium metal is less dense than water.īecause of this reason, the sodium metal floats on water. Sodium has a density of 0.97 g/cm 3, while water has a density of 1 g/cm 3. Now let’s see about sodium metal and it’s density. And if the density of object is less than the water, then it will float on water. If the object has a density higher than the water, then it will sink. You might have studied the concept of density in physics.īy knowing the density of two objects, we can come to know which object will float and which will sink in water.
