The nucleus _n^m X emits one particle and 2 -particles. The resulting nucleus is

Options

  1. Aaligned & m-4 & n-2 aligned Y
  2. Baligned & m-6 & n-4 aligned Z
  3. C_n^ m-6 Z
  4. D_n^ m-4 X

Correct answer

D. _n^ m-4 X

Step-by-step solution

Emission of -particle decreases the mass number and the atomic number by 4 and 2 respectively. Emission of -particle increases the atomic number by 1 while the mass number remains unchanged. After the emission of the one -particle and two -particles Decreases in mass number =4-0=4 Decreases in atomic number =2-2=0 The resulting the nucleus is m-4, X . i.e. the isotope of the given nucleus.
