92238U{ }_{92}^{238} \mathrm{U} emits 8α8 \alpha-particles and 6β6 \beta-particles. The neutron/proton ratio in the product nucleus is

Options

  1. A60/4160 / 41
  2. B61/4061 / 40
  3. C62/4162 / 41
  4. D61/4261 / 42.

Correct answer

C. 62/4162 / 41

Step-by-step solution

92U238−6β−8α82X206{ }_{92} \mathrm{U}^{238} \stackrel{-8 \alpha}{-6 \beta}{ }_{82} X^{206} Number of protons =82=82 Number of neutrons =124=124 Neutron/proton ratio in the product nucleus =12482=6241=\frac{124}{82}=\frac{62}{41}
