Science / Chemistry / Fission: A nuclear reaction in which an atomic nucleus breaks into smaller nuclei of comparable mass, releasing a large amount of energy.

Nuclear Fission

Science / Chemistry / Nuclear Fission: Splitting of a nucleus into two smaller nuclei and neutrons. The smaller nuclei have higher binding energy than the original nucleus, and fission results in the release of energy. MORE

Binary Fission

Science / Biology / Binary Fission: The method by which bacteria reproduce. The circular DNA molecule is replicated; then the cell splits into two identical cells, each containing an exact copy of the original cells DNA. MORE
