Hi,
The ancient Greeks were the first people to come up with the idea that everything was made up of tiny particles. A rich philosopher called Democritus developed a theory of 'atoms'. Democritus thought of his 'atoms' as having different shapes and sizes to explain the different properties of everyday materials. For example, water 'atoms' were thought to be smooth and round (because water flows easily). But iron 'atoms', according to Democritus, were probably sharp and jagged (because iron is hard, so its atoms can't move past each other easily). An essential part of Democritus' theory was that these 'atoms' could not be broken up into still smaller particles (in fact, ' atom' comes from a Greek word meaning 'cannot be cut'). While some thinkers liked his ideas, many others did not believe this part of his theory, so people lost interest in the theory for many centuries.
Part of the problem, of course, was that nobody could see any of these particles. Atoms are far too small for that! And that is still true today, although we now have very powerful machines that enable us to see images that correspond to particles. A new industry is being developed, called 'nanotechnology', that uses the latest scientific instruments to move even single atoms around and position them precisely.
Hoping it helps

HEYA ,HERE IS YOUR ANSWER
Any matter is made up of small particles as if we take small piece of sugar and drop down into a glass which is filled with water after sometime it can't be seen because small piece of sugar is made up of tiny atoms which can't be seen with naked eye. This proofs that any matter in the world is made up of small particles which can be seen under special intruments called microscope.
