Wait a minute. Atoms are easily broken up. It's quite easy to shred atoms by pulling the negative electrons away from the tiny positive nucleus in the center of an atom. When we rubbed the balloon on our hair, we were pulling atoms apart. We should not think of atoms as if they were unbreakable little solid balls.
Atoms are more like liquid droplets made of electrical charge.
When atoms come together to form everyday objects, the charges which form the outside of the atoms get all mixed together. It's as if the world was made of charged particles, half of them being the negative electrons, and the other half being the positive cores of atoms. Then we would have an electric current. Now you know what an electric current really is. It's that simple.
