If a molecule is made of only one type of atom, then it is a pure element in molecular form. For example, hydrogen gas, as it was used in balloons before the Hindenburg caught fire, is a pure element. That gas consists of hydrogen molecules - H2. Hydrogen gas nearly always forms two-atom molecules and is still a pure element.
The Oxygen in the air is a pure element but it also is only found as two-atom gas-molecules - O2.
The well-known Buckyballs which are large molecules of carbon are nothing but carbon and therefore are molecules of one element - pure carbon.

Molecules and elements are not the same thing. There are many molecules in elements but not elements inside of molecules.
Are elements and compounds made of atom?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).
