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
