Compute the binding energy per nucleon for H (whose atom has a measured mass of 3.016050 u) 3He (3.016029 u),JHe (4.002603 u), Li (6.015123 u), and 3Li (7.016004 u). Note how extraordinarily strongly bound the average nucleon in 4He is compared to its neighboring nuclei. Describe some the advantages that4He has over its neighbors that might explain its exceptionally tight binding
