A radioactive element \({ }_{92}^{242} \mathrm{X}\) emits two \(\alpha\) particles, one electron and two positrons. The product nucleus is represented by \({ }_{\mathrm{P}}^{234} \mathrm{Y}\). The value of P is
- A 87
- B 85
- C 92
- D 96
Answer & Solution
Correct Answer
(A) 87
Step-by-step Solution
Detailed explanation
\( P = 92 - (2 \times 2) + 1 - (2 \times 1) \) \( P = 92 - 4 + 1 - 2 \)
