3 ATOM COUNT. It is hard to grasp just how small the atoms that make up your body are until you take a look at the sheer number of them. An adult is made up of around 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms.
In fact, atoms are decaying around you all the time. You can't cut one apart, but your body has a number of radioactive carbon, potassium, and other atoms. They decay all the time, and you don't notice it, because the energy involved is insignificant. To make it clear, you can't split an atom with a knife.
