what is one benefit with a nuclear fission reaction
a large amount of energy is produced
Which nuclear emission has the greatest mass and the least penetrating power
alpha particle
Which nuclear emission has the least penetrating power and the greatest ionizing ability?
alpha particle
Which list of nuclear emissions is arranged in order from the least penetrating power to the greatest penetrating power?
alpha particle, beta particle, gamma ray
When an atom of the unstable isotope Na-24 decays, it becomes an atom of Mg-24 because the Na-24 atom spontaneously releases
beta particle
Which particle has the least mass?
beta particle
which radioisotope is used to determine the age of once living organisms?
carbon 14
In which process does a heavy nucleus split into two lighter nuclei
fission
which term identifies a type of nuclear reaction
fission
Which process converts mass into energy
fusion of hydrogen atoms
Which change occurs during a nuclear fission reaction
matter is converted to energy
Cobalt-60 and iodine-131 are radioactive isotopes that are used in
medical procedures
which group of nuclear emissions is listed in order of increasing charge
neutron, positron, alpha particle
The dating of geological formations is an example of a beneficial use of
radioactive nuclides
what occurs in both fission and fusion reactions
small amounts of matter are converted into large amounts of energy
when a large unstable nucleus spontaneously splits into two (or occasionally three)
spontaneous fission
the conversion of one chemical element or an isotope into another chemical element.
transmutation
which term represents a nuclear reaction
transmutation
State evidence that this nuclear reaction represents transmutation
uranium is changing to other reactions
Explain in terms of elements, why the decay of Bi-210 is considered a transmutation
A different element forms
which radioisotope is used for diagnosing thyroid gland disorders
Iodine-131
Explain in terms of protons and neutrons, why U-238 and U-234 are different isotopes of uranium.
These two atoms have the same number of protons but a different number of neutrons
which radioisotope is used in dating geological formations
U-238
