What is salt made of?
There is a soft, lightweight metal called sodium which we never see because it bursts into flames in air and can even burn under water. There is a greenish gas called chlorine that we never smell because it is poisonous and which can only exist in pure form because it quickly combines with almost every other element it’s exposed to. If you got some pure sodium and exposed it to pure chlorine in a container, it would burn at a very high temperature. The ashes left over would be little cubes of salt stuck together. Yes, these two deadly poisonous and dangerous substances become common table salt which we need every day of our lives.
