Which is a characteristic of nuclear fission?

releases nonradioactive waste only
involves the collision of two nuclei
releases small amounts of energy compared to fossil fuels
involves the splitting of an atom into two or more fragments

answer:

in nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.   when an atom of nuclear fuel (uranium) absorbs a neutron, the uranium will fission into two smaller atoms (waste) and release one to three neutrons. the kinetic energy of the waste is used to heat the water for the steam turbine. the neutrons are used to fission the next lot of uranium atoms and the process continues. nuclear fission is the process in which a large nucleus splits into two smaller nuclei with the release of energy. in other words, fission the process in which a nucleus is divided into two or more fragments, and neutrons and energy are released.
