15-30
when u-238 emits an alpha particle, the nucleus left behind has
90 protons
when uranium emits a beta particle, the result is
a transuranic element
energy released by the sun results from the process wherein atomic nuclei
combine
in both fission and fusion, mass
is changed to the form of kinetic energy
when two light atoms fuse together, mass
is converted to kinetic energy of neutrons
compared to the sum of the masses of all the individual nucleons in their separate states that make up a nucleus, the mass of the composite nucleus is
less
when u-239 emits a beta particle, the nucleus left behind has
93 protons
between nuclear fission and nuclear fusion, radioactive by-product are more characteristics of nuclear
fisson
a nuclear process that has relatively few radioactive by-products is
fusion
a proton has the greatest mass in the nucleus of
hydrogen
a nucleon has the least mass in the nucleus of
iron
the nucleus with the most tightly bound nucleon is
iron
the mas of a nucleus is exactly equal to the um of the masses of its individual
none of these
in which of these processes is an element of matter changed into a completely different element?
nuclear fission and nuclear fusion
the nucleus with the greatest mass is
plutonium
when u-235 undergoes fission, the two nuclei that result have a total of
92 protons
