The masses of a potassium-40 atom, a proton and a neutron are 39.963999 amu, 1.007825 amu and 1.008665 amu, respectively. Calculate to four significant figures the mass defect in amu and the energy released in MeV/nucleon, in the formation ofK1940from the appropriate number of protons and neutrons.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

did anyone actually do this? like if anyone has submitted this i rly need .
