A nucleus with atomic mass number ' A ' produces another nucleus by loosing 2 alpha particles. The volume of the new nucleus is 60 times that of the alpha particle. The atomic mass number A of the original nucleus is
Options
- A228
- B238
- C248
- D244
Correct answer
C. 248
Step-by-step solution
_Z^A X - - particle _ Z -2 ^ A -4 Y - - particle _ Z -4 ^ A -8 R Volume of R =60 ( . Volume of . ₂^4 He ) 4 3 r₁^3=60 4 3 r₂^3 (R₀ A₁^ 1 3 )^3=60 (R₀ A₂^ 1 3 )^3 ( A -8)=60 4 A=248
