Nuclei Test - 5...

In a fission reaction $$^{236}_{92}U \rightarrow ^{117}X+^{117}Y+n+n$$. The binding energy per nucleon of $$X$$ and $$Y$$ are  $$8.5 MeV$$ whereas of $$^{236}U$$ is $$7.6 MeV$$. The total energy liberated will be about

Consider the nuclear reaction $$X^{200}\rightarrow A^{110}+B^{90}$$ if the binding energy per nucleon for X, A and B is 7.4 MeV, 8.2 MeV and 8.2 Mev respectively, what is the energy released?

Electrons are bombarded to excite hydrogen atoms and six spectral lines are observed. If $$E_{g}$$ is the ground state energy of hydrogen, the minimum energy the bombarding electrons should possess is

A $$1.0\ MeV$$ neutron emitted in a fusion loses one half of its kinetic energy in each collision with a moderator  molecule. Number of collision it must be more to reach thermal energy will be $$\left(Take, \dfrac {3}{2}k_{B}T=0.040\ eV\right)$$    

Complete the equation for the following fission process $$_{92}U^{235}+_{0}n^{1}\rightarrow _{38}Sr^{90}+...$$

The reactor produced a power of $$10^{10}\ MW$$ with $$50$$% efficiency. Then the number of deutrons required to run the reactor for one year will be approximately:    
$$m\left( _{ 1 }^{  }{ { H }_{  }^{ 2 } } \right) =2.014\ u,m\left( p \right) =1.007\ u,m\left( n \right) =1.008\ u,m\left( _{ 2 }^{  }{ { H }e_{  }^{ 4 } } \right) =4.001\ u$$

The energy of the reaction $$Li ^ { 7 } + p \longrightarrow _2He^4$$ is (the binding energy per nucleon in $$Li^7$$ and $$He^4$$ nuclei are $$5.60$$ and $$7.06\ MeV$$ respectively.)

To start an endoergic reaction, a stationary nucleus $$(x)$$ in bombarded by a neutron $$(n)$$ to produce nuclei $$Y$$ and $$Z$$ in the final state. Choose the correct option from the following statements related to this reaction.

Atomic mass of $$_{ 6 }^{ 13 }{ C }$$ is $$13.00335$$ amu and its mass number is $$13.0$$. If amu $$=931$$MeV, the binding energy of the neutrons present in the nucleus is 

Nucleus of an elements contains 9 protons. It's valency would be:
