What is meant by ion?

@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.

any atom having a charge is ion

@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).

What's the difference b/w molecule and compound?

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

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...)

ION is nothing but either positive or Negative charge.

Raj said: (Aug 9, 2012)  
Ion is nothing but a charged atom when it looses or gains an electron.

Jay said: (Sep 27, 2012)  
Is H2O a compound as well as a molecule?

Divyashree said: (Aug 27, 2013)  
Water is a compound. Every molecule of water is made of two atoms of hydrogen and one atom of oxygen.

Amol said: (Aug 25, 2014)  
I think the answer is wrong. How mixture is equal to compound?
The mixture of salt and sugar is not a compound.

Can anyone able to explain? Please explain.
