When uranium-235 is hit with a slow-moving neutron, it absorbs it and temporarily becomes the very unstable uranium-236. This nucleus splits into two medium-mass nuclei while also emitting more neutrons. The mass of the products is less than the mass of the reactants, with the lost mass being converted to energy.

You need to use the neutron gun to fire a neutron at the atom. This changes U-235 to U-236 through the addition of a neutron. U-236 is unstable and quickly fissions into two daughter nuclei. “Unstable” means that the nucleus has too many neutrons to hold itself together.

In nuclear fission, atoms are split apart, which releases energy. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation.

Answer and Explanation: Uranium-235 decays into thorium-231 through alpha particle emission. As thorium-231 is also an unstable isotope, the atom will continue to decay until it finally reaches a stable state as an atom of lead-207.

The heat released in fission can be used to help generate electricity in power plants. Uranium-235 (U-235) is one of the isotopes that fissions easily. During fission, U-235 atoms absorb loose neutrons. This causes U-235 to become unstable and split into two light atoms called fission products.

As a result, it splits into two smaller nuclei, krypton-92 and barium-141. The reaction also releases three neutrons and a great deal of energy. It can be represented by this nuclear equation: 92 235 U + 1 neutron → 36 92 K r + 56 141 B a + 3 neutrons + energy.

Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. In a nuclear reactor , a neutron is absorbed into a nucleus (typically uranium-235). This causes the nucleus to become uranium-236, which is violently unstable. The entire nucleus splits into two large fragments called 'daughter nuclei '.

The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts.
