Since α rays has more charge than β and γ has no charge therefore order of ionization is α > β > γ.
The correct answer is: α > β > γ
The binding energies of the nuclei P^{n} and Q^{2n} are x and y joules. If 2x > y then the energy released in the reaction P^{n} + P^{n} → Q^{2n}, will be
The correct answer is: (2x  y)
A radioactive element Th(_{84}Po^{216}) can undergo α and β are type of disintegration with half lives, T_{1} and T_{2} respectively. Then the half life of Th is .
The correct answer is:
The order of magnitude of the density of nuclear matter is :
The correct answer is: 10^{17} kg/m^{3 }
The value of binding energy for _{1}H^{2}, _{2}He^{4}, _{28}Fe^{56}, _{92}U^{235} are 2.22, 28.3, 492 and 1786 units respectively. The most stable nucleus is :
The correct answer is: _{28}Fe^{56}
The correct answer is: 1Ci
In equation _{92}U^{235} + _{0}n^{1 }→ _{56}Ba^{144} + _{36}Kr^{89} + X ; X is :
The correct answer is: 3 _{0}n^{1}
Nuclear fission equation
_{92}U^{235 }+ _{0}n^{1 }→ _{56}Ba^{144} + _{36}Kr^{89} + 3 _{0}n^{1 }
Hence particle x is neutron.
Masses of nucleus, neutron an protons are M, m_{n} and m_{p }respectively. If nucleus has been divided into neutrons and protons, then
The correct answer is: M < (A  Z)m_{n} + Zm_{p}
In most stable nuclei neutron number N and proton number Z has the relation
The correct answer is: N ≥ Z
