A molecule is made up of at least 2 atoms.A compound is made up of 2 or more different elements.Oxygen(O2), Ozone(O3)Nitrogen(N2) are molecules not compounds as they are composed of only one element.
So all compounds are molecules but not all molecules are compounds.

Hydrogen, Oxygen and Nitrogen for example, exist as 'Diatomic Molecules'...H2, O2 & N2. These are pure Elemental Molecules NOT Compounds which are composed of 2 or more different pure Elements to produce a compound of a different substance, the properties of which will be totally different to those of the elements of their make-up.
A simple example is that of Sodium and Chlorine....both deadly in their own right.
When chemically combined into Sodium Chloride (NaCl) we have an innocuous compound of Common Salt.

A molecule consists of two or more atoms bounded together. A molecule of nitrogen gas is N2; So a nitrogen molecule is composed of two atoms of the same element , nitrogen.
Oxygen molecule is O2.
For a compound, the atoms bound together forming the molecule are not all the same element. For example , water is H2O. Sulphuric acid is a compound and is H2SO4.

Compounds can be either ionic or molecular. Ionic compounds do not have molecules as their smallest particles, just ions and ion combinations. Molecular compounds have, obviously, molecules as their smallest particles. So the compound is the identity of the substance, and the molecule is its smallest particle that still has the complete properties of the compound.

Molecules make up a compound

The basic difference is that a molecule is made up of two atoms chemically bonded.
A compound is a molecule that is made up of two different elements.
Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2) are not compounds because they are each made up of one element.
Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds because each of them are made up of more than one element.

A molecule is primarily composed of mono and binary non-metallic ions (e.g. H2O is composed of H+ and OH-; NH4OH is composed of NH4+ and OH- ions)whereas compounds are composed of metalic ions and nonmetallic ions compounded together (ex. NaCl is composed of Na+, a metal cation and Cl- a non-metal anion)
