Which outcome reduces binding energy per nucleon in helium?

A)Alpha decay emits many photons

B)Symmetric fission creates smaller nuclei✓

C)Beta decay reduces nucleus stability

D)Nuclear fusion assembles very heavy isotopes

💡 Explanation

Symmetric fission decreases binding energy per nucleon because, via the liquid drop model, the heavy nucleus splits more mass efficient medium sized nuclei, and nucleon configurations become more stable; therefore, post fission nuclei are lighter rather than alpha or beta radioactivity or fusion.
