@Ramya
An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.

@xyz
A substance in which the atoms of two or more elements have united chemically to form a molecule.
For example, an atom of cadmium (Cd) and one of sulfur (S) combine to form a
molecule of cadmium sulfide (CdS).

A compound is a type of molecule. A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Not all molecules are compounds, since some molecules, such as hydrogen gas or ozone, consist only of one element or type of atom.
Molecule Examples: H2O, O2, O3
Compound Examples: NaCl, H2O
Molecule Examples: H2O, O2, O3

A molecule is when two or more atoms join together. A compound is a molecule that contains at least two different elements.

Element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...)
Atom - the smallest amount of an element
Molecule - two or more atoms that are chemically joined together (H2, O2, H2O, etc...)
Compound - a molecule that contains more than one element (H2O, C6H12O6, etc...)
