Everything You'll Have Covered

What is a compound?

~ A compound is a substance composed of two or more elements that have been combined together chemically.

Why can't sodium and chlorine, individually, be used as a substitute for sodium chloride (table salt)?

~ Individually, sodium and chlorine are very dangerous substances. Sodium becomes explosive when it comes in contact with water, and chlorine is poisonous. It is only when these elements combine to form sodium chloride that they become safe to eat.

How does this phenomenon also apply to water?

~ Water is a compound composed of hydrogen and oxygen. Like sodium and chlorine, hydrogen and oxygen can be very dangerous, as hydrogen is very flammable and pure oxygen can be toxic. However, when combined, they form water, a perfectly safe compound with very different chemical properties.
