Atomic explosion is triggered by - (1) thermo nuclear reaction (2) chemical reaction (3) controlled chain reaction (4) uncontrolled chain reaction

1 Answer

Answer :

(4) uncontrolled chain reaction Explanation: During an uncontrolled nuclear chain reaction such as atomic explosion, a radioactive substance gives off energy at a rate that increases rapidly with time, leading to large amounts of radiation and possibly an explosion. The radioactive decay of one atom triggers the decay of some of its neighbors, in turn setting off other atoms; thus, producing large amounts of energy.
