. What does it mean to say that fissionable material possesses a critical mass? Can a chain reaction occur when a sample has less than the critical mass?
Interpretation:
Interpret the statement ‘fissionable material possesses critical mass’. Interpret whether chain reaction takes place if sample has less than critical mass.
Concept Introduction:
The atom consists of nucleus and the electrons. The nucleus of an atom consist of proton and neutron and the electron is revolving around the nucleus. Mass number of an atom is equal to the sum of number of protons and neutrons. Atomic number is equal to the number of protons or in ground state it is also equal to the number of electrons.
Critical mass is the minimum mass of the reactant or nuclide required for its reaction for fission. A reactant is needed in critical amount such as limiting reagent so to proceed the reaction to get the yield of product...
