How are lighter elements formed
WebThe reaction is therefore a fusion of two carbon-12 nuclei, and no other particles are produced: 12 6 C + 126 C → 2412Mg. The neon-20 product has Z = 10 and A = 20. The conservation of mass requires that the other product have A = (2 × 12) − 20 = 4; because of conservation of charge, it must have Z = (2 × 6) − 10 = 2.
