The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.


What is the difference in a nuclear power plant and a nuclear bomb?

A nuclear power plant uses a slow, controlled nuclear chain reaction to heat water and generate electricity. A nuclear bomb uses a very rapid uncontrolled nuclear chain reaction in order to generate a massive explosion.


What are the various differences between a stable and an unstable nuclei?

The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.


How is the chain reaction different in a nuclear bomb compared to a nuclear power-plant?

in a bomb it is an uncontrolled runaway reaction that completes in roughly 10 microseconds with the detonation of the core of the bomb.in a reactor it is a controlled steady reaction that continues for hours to years, until the operators shut the reactor down for maintenance.


Why is this so that million of alpha particles bombarded on beryllium will produce only 30 neutrons?

When alpha particles are bombarded on beryllium, the process that occurs is known as the (α, n) reaction. In this reaction, the alpha particle collides with a beryllium nucleus, causing it to absorb the alpha particle and become an unstable nucleus. This unstable nucleus then decays, emitting a neutron. The probability of this reaction occurring is relatively low, which is why not all alpha particles result in neutron production.

What type of reaction is taking place when Butane burns to produce a flame?

The combustion of butane to produce a flame is a chemical reaction known as a combustion reaction. In this reaction, butane reacts with oxygen to produce carbon dioxide, water, and heat energy.


What is the formula for the chemical reaction for oxygen and hydrogen?

2H2 + O2 -> 2H2O - reaction to produce water H2+O2-> H2O2 - reaction to produce hydrogen peroxide


How is the chain reaction in a nuclear reactor different from one in an atomic bomb?

In a nuclear reactor, the chain reaction is controlled to produce a steady flow of energy by regulating the rate of reactions. In an atomic bomb, the chain reaction happens rapidly and uncontrollably, resulting in a massive release of energy in a short period of time, leading to an explosion.
