Question

In the given nuclear process, particle \( W \) is: \[ ^2\text{He}^4 + _zX^A \rightarrow _{z+2}Y^{A+3} + W \]

• A. neutron
• B. proton
• C. electron
• D. positron

Hint:

Use conservation of mass and atomic number to identify unknown particles.

Answer 1

The Correct Option is B

Step 1: By balancing atomic number and mass number: \[ 4 + A = (A+3) + 1 \] Step 2: This indicates that the emitted particle is a proton. \[ \boxed{\text{Proton}} \]
