Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.

- Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
- Examples are copper, gold, iron
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
- There are several millions of compounds known.
- They are usually represented by chemical formulae.
As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.
