The nucleus of 6Li is a powerful absorber of neutrons. Itexists in the naturally occurring metal to the extent of7.5%. In the era of nuclear deterrence, large quantitiesof lithium were processed to remove 6Li for use in hydrogenbomb production. The lithium metal remaining afterremoval of 6Li was sold on the market. (a) What are thecompositions of the nuclei of 6Li and 7Li? (b) The atomicmasses of 6Li and 7Li are 6.015122 and 7.016004 amu, respectively.A sample of lithium depleted in the lighter isotopewas found on analysis to contain 1.442% 6Li.
