Find the energy required to split ₈O¹⁶ nucleus into four α- particles. The mass of an α – particle is 4.002603 u and that of oxygen is 15.994915 u.

Q: Find the energy required to split ₈O¹⁶ nucleus into four α- particles. The mass of an α – particle is
4.002603 u and that of oxygen is 15.994915 u.

Sol: Mass of a particle = 4.002603 u

Mass of oxygen = 1.5994915 u

B.E = [Mass of 4 particle – Mass of oxygen] × 931.5 MeV

B.E = [4 × 4.002603-15.994915] × 931.5 MeV

= (16.01412 – 15.994915) × 931.5 MeV

= 0.15497 × 931.5 ; B.E = 14.43 MeV.
