Here's why:

* Elements are the simplest pure substances that cannot be broken down into simpler substances by ordinary chemical means. They are the building blocks of everything around us. Examples include:

* Hydrogen (H)

* Oxygen (O)

* Carbon (C)

* Gold (Au)

* Iron (Fe)

* Compounds are formed when two or more elements chemically combine in a fixed ratio. They can be broken down into their constituent elements. Example: Water (H₂O) can be broken down into hydrogen and oxygen.
