The energy released if hydrogen atoms are combined to form ^4_2He is ______ MeV. (Take binding energies per nucleon of ^2_1H and ^4_2He as 1.1 MeV and 7.2 MeV, respectively)

(B) 24.4. Concept. Fusing two deuterons into helium releases the gain in total binding energy. Step 1. Before. 2×2×1.1=4.4 MeV. Step 2. After. 4×7.2=28.8 MeV. Step 3. Released. 24.4 MeV. Answer. Option B.
