Nuclear reaction products identification requires diagram details

Steps:

• Examine the diagram for reactant and product particles, noting shaded unchanged ones.
• Identify emitted particles in products based on nuclear notation (atomic number, mass number).
• Match products to options: helium atom (neutral He) vs. nucleus (He²⁺, alpha particle), and proton (¹H⁺) vs. neutron (n).
• Verify conservation of charge and mass to confirm.

Not enough information: Diagram absent, preventing particle identification.

Final answer: Not enough information.
