Molecular formula :
nature : a nucleus of a very good quality to split a few pieces of debris, usually confined to a heavier nucleus, such as uranium, plutonium and thorium isotopes nuclear. Fissile are spontaneous and induced two. Spontaneous heavy nuclei is not a manifestation of stability, a very long half-life, such as uranium is about 238 million years. Referring to the nucleus induced by the other particle bombardment immediately when fission, such as uranium 235 by the thermal neutron bombardment when they split. Nuclear fission release enormous energy.
