How much energy is released in the following reaction: 7 Li + p → α + α. Atomic mass of 7 Li = 7.0160 u and that of 4 He = 4.0026 u.

Question

Philoid · Accepted Answer

Given,

Atomic mass of ⁷Li = 7.0160 u

Mass of proton = 1.007276 u

Atomic mass of ⁴He = Mass of α particle = 4.0026 u

∴

So, ΔM = 0.018076u

Binding Energy [Where ]

Hence, the binding energy for the reaction is 16.83 MeV
