If not.. you basically need to impart more energy into the atom than is keeping the nucleus together. There are 4 kinds of forces in nature: Electromagnetism (the thing that gives you shocks), Gravity (the thing that makes you fall) …and two more – the weak nuclear force, and the strong nuclear force. The strong nuclear force is what binds all the protons in the nucleus together. It’s…very, very strong. It’s about 10000000000000000000000000000000 times stronger than gravity. If you can break that force, you can split an atom.
