Final answer:

Atoms are the building blocks of elements, while molecules and compounds are formed through the combination of atoms with distinct characteristics.


Explanation:

Atoms are the basic units of elements, with each element having its own specific type of atom. When atoms chemically bond together, they form molecules, which can be made of either the same type of atom in the case of elements or multiple types in the case of compounds. Compounds are composed of atoms from two or more elements, always present in whole-number ratios.
