chain reaction

series of reactions in which each is directly caused by the one before it

A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place.The neutron-fission chain reaction: a neutron plus a fissionable atom causes a fission resulting in a larger number of neutrons than was consumed in the initial reaction.Chemical reactions, where a product of a reaction is itself a reactive particle which can cause more similar reactions. For example, every step of  H₂ + Cl₂ chain reaction consumes one molecule of H2 or Cl2, one free radical H· or Cl· producing one HCl molecule and another free radical.Electron avalanche process: Collisions of free electrons in a strong electric field  forming "new" electrons to undergo the same process in successive cycles.

Noun
1. a series of chemical reactions in which the product of one is a reactant in the next
(hypernym) chemical reaction, reaction
2. a self-sustaining nuclear reaction; a series of nuclear fissions in which neutrons released by splitting one atom leads to the splitting of others
(hypernym) nuclear reaction

A chain of events described by W. Edwards Deming: improve quality, decrease costs, improve productivity, increase market with better quality and lower price, stay in business, provide jobs and provide more jobs.

A reaction that initiates its own repetition. In a fission chain reaction, a fissionable nucleus absorbs a neutron and fissions spontaneously, releasing additional neutrons. These, in turn, can be absorbed by other fissionable nuclei, releasing still more neutrons. A fission chain reaction is self-sustaining when the number of neutrons released in a given time equals or exceeds the number of neutrons lost by absorption in nonfissionable material or by escape from the system.
