In the process of nuclear fission,1__one atom splits___.Fission only happens to very 2(__large___) atoms.The Fission process usually also produces several free 3(__neutrons___).
Nuclear fission is a radioactive decay process in which heavy and unstable radioactive nucleus decays into lighter ones with the release of energy and free neutrons.
Fission differs from fusion in that in nuclear fusion, two light atoms comes together to form a large one. This process releases a very great amount of energy.
The area where the periodic table has the highest electronegativity are Groups 1 and Groups 7 because they are close on giving away an electron and the other is close to becoming stable.
