    We can say this, based on historical experiments over the years such that it has become common knowledge.

    The most famous of which is the Rutherford model:

    Later the Bohr model explained why electrons can orbit without losing energy which was the birth of Quantum Mechanics and our present understanding.

    Then there's the brownian motion explanation from Albert Einstein where invisible atoms are colliding particles of dust causing them to skitter about randomly.
