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 'atomos', meaning indivisible. Using a gold block as an example, the video illustrates that dividing it repeatedly will eventually lead to a single atom, which cannot be further divided without losing its elemental properties. An analogy with balloons is used to further explain this concept, emphasizing that an atom is the smallest unit retaining the characteristics of an element.
