In successive emission of -and -particles, the number of -and -particles should be emitted for the conversion of ₉₂ U ²³⁸ to ₈₂ ~Pb ²⁰⁶ are

Options

  1. A7 , 5
  2. B6 , 4
  3. C4 , 3
  4. D8 , 6

Correct answer

D. 8 , 6

Step-by-step solution

₉₂ U ²³⁸ ₈₂ ~Pb ²⁰⁶+m₂ He ⁴+n_ -1 e⁰ On comparing both sides aligned 238 &=206+4 m m &=8 92 &=82+2 m-n 2 m-n &=10 n &=6 aligned -particles emitted, m=8 -particles emitted, n=6
