An atom has an atomic number of 12 and a mass number of 25. how many neutrons does the atom have? How many atoms are in 54.6 g of nickel? How many atoms are in 3.5 moles of arsenic? How many atoms of C are present in 58.6 g of C_6H_6?
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, ...
and in the process, it becomes two atoms. 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). ...
