CHAIN FISSION

fission (a splitting apart or dividing) of larger atoms such as atoms of uranium into smaller atoms such as atoms of iodine and bromine. This process can be designed so that each fission will cause another fission, thereby setting off a chain reaction. The atomic bomb is an example of a chain fission. —PDC Volume 3 Approved Glossary

fission (a splitting apart or dividing) of larger atoms such as atoms of uranium into smaller atoms such as atoms of iodine and bromine. This process can be designed so that each fission will cause another fission, thereby setting off a chain reaction. The atomic bomb is an example of a chain fission.(fission means a splitting apart, dividing) larger atoms such as atoms of uranium can fission (split) into smaller atoms such as atoms of iodine and bromine. This process can be designed so that each fission will cause another fission, thereby setting off a chain reaction. The atomic bomb is an example of a chain fission. Used figuratively.
