* Compounds are formed by the chemical combination of two or more elements. This means that a compound cannot exist without having at least two elements as its building blocks.

Think of it like this:

* Elements are the basic building blocks of matter (like hydrogen, oxygen, carbon).

* Compounds are like recipes that combine these elements in specific ratios (like water, which is H₂O, or carbon dioxide, which is CO₂).
