What Is An Atom ?

The video explains that everything is made of atoms, which are extremely small and indivisible. The term 'atom' originates from the Greek word 'atomus'. Using gold as an example, the video illustrates how dividing a block of gold repeatedly will eventually result in a single gold atom. An analogy with balloons is used to further explain this concept. The video concludes by stating that an atom is the smallest unit of an element that retains all its properties.
