Here's why:
* Elements are the simplest pure substances that cannot be broken down into simpler substances by chemical means. They are the building blocks of everything. Examples include carbon, oxygen, hydrogen, and gold.
* Molecules are formed when two or more atoms bond together. While molecules are essential for forming the matter we encounter, they are ultimately made up of elements. For example, water (H₂O) is a molecule made up of two hydrogen atoms and one oxygen atom.
Therefore, elements are the fundamental building blocks, and molecules are combinations of these elements.
