Which of the following nuclear fragments corresponding to nuclear fission between neutron (¹₀n) and uranium isotope (²³⁵₉₂U) is correct?
Asked in JEE Main 4th April 1st Shift 2024 · Energy released in fission and fusion
- (1) ¹⁴⁴₅₆Ba+⁸⁹₃₆Kr+3 ¹₀n
- (2) ¹⁵³₅₁Sb+⁹⁹₄₁Nb+3 ¹₀n
- (3) ¹⁴⁴₅₆Ba+⁸⁹₃₆Kr+4 ¹₀n
- (4) ¹⁴⁰₅₆Xe+⁹⁴₃₈Sr+3 ¹₀n
Answer: (1) ¹⁴⁴₅₆Ba+⁸⁹₃₆Kr+3 ¹₀n
Step-by-step solution
Reactants: A=236, Z=92.
Option 1: 144+89+3=236 and 56+36=92: balanced.
→ option 1
Why the other options are wrong
- (2) Mass number totals 255, not 236.
- (3) Mass number totals 237.
- (4) Charge totals 94, not 92.
