What is an Atom?

An atom is the smallest possible amount associated with a chemical element. For example, an atom of gold can be called as the smallest quantity of gold you can feasibly have. The word ‘small’ literally points out to nanoscopically tiny! An atom is thousands of times smaller than a human hair.

Existence of an Atom.

It might seem as if there's a simple way to prove atoms exist: put them under the microscope. But this approach won't work.
