energy released
Explanation:
energy released is determined by using following relation
energy released = mass defect * c^2
mass defect is obtained as
mass defect = mass of reactants - mass of products
mass of reactants = 4* mass of helium
mass of products = Mass of alpha particle
therefore mass defect is
mass defect = 4 * 1.007825 - 4.002603
mass defect = 0.028697 u
hence, energy released = mass defect * c^2
energy released
