Question

calculate binding energy of alpha particle in erges . given mass of a proton,neutron and helium nucleus as 1.00758,1.00897 and 4.09820 amu respectively. ​

Answer 1

Answer:

please mark it as brainlist my friend

Explanation:

The alpha particle has two proton and two neutron.

The combined mass of nuclei =net mass of proton + net mass of neutron =(2×1.007277)+(2×1.00866)=4.031874 amu

Binding energy = mass defect =4.031874−4.001265=0.0306amu=0.0306(931.48)=28.5MeV
