MOLECULE - SIMPLE DEFENITON , SIMPLE TERMS

MOLECULES

                              In simple terms we speaking, a general molecule is an electrically neutral group of two or more atoms held together by chemical bonds.  There are atoms holding another atom one by one with a help of a chemical bond.

In the above diagram we can see that a single atom of oxygen and two atoms of hydrogens chemically bonded together to make H2O-water. 

Therefore, like this an atoms can be bonded to make an single molecule.
