How many atoms of cobalt equal a mass of 58.93 g? How many valence electrons does a neutral atom of aluminum have? How many protons, neutrons, and electrons are in aluminum? How many neutrons does aluminum have? How many atoms are in 2 Fe?
For example, one fermium-256 atom may become a xenon-140 and a palladium-112 atom, and in the process it will eject four neutrons (known as "prompt neutrons" because they are ejected at the moment of fission). These neutrons can be absorbed by other atoms and cause nuclear reactions, ...

It has been suggested that extremely neutron rich nuclei constitute a second branch of the table of isotopes whose ground states have the maximum possible isospin Tmax = A/2 and that neutral members of the T max branch (i.e., polyneutrons) serve as mediating particles for the new class ...
