Answer

D

Step-by-step solution

2 steps

1. The definition:
The definition provided describes the Relative atomic mass. It compares the average mass of an atom of an element to 112\frac{1}{12} the mass of a carbon-12 atom.

  • The correct option is D.

2. Nuclear reaction:
For the nuclear reaction 3788Z+24He→srY+2−10β^{88}_{37}\text{Z} + ^4_2\text{He} \rightarrow ^r_s\text{Y} + 2^0_{-1}\beta:

  1. Conserve the mass number (superscript).

    88+4=r+2(0)88 + 4 = r + 2(0) 92=r92 = r
  2. Step 2
