Nuclear Chemistry

Front

nuclear change

Back

a change in the nucleus of an atom

Front

radioactive

Back

elements that spontaneously emit radiation

Front

Isotope

Back

Atoms of the same element that have different numbers of neutrons

Front

nuclear decay

Back

a process that occurs when an unstable atomic nucleus changes into another more stable nucleus by emitting radiation

Front

alpha emission

Back

radioactive decay that releases alpha particles

Front

beta emission

Back

when a neutron changes into a proton and an electron and the electron is released

Front

gamma radiation

Back

High-energy radiation (a photon) emitted by the nuclei of radioactive atoms

Front

Fission

Back

The splitting of an atomic nucleus to release energy.

Front

Fusion

Back

Creation of energy by joining the nuclei of two hydrogen atoms to form helium.

Front

Half-life

Back

The time required for half of the atoms in a radioactive sample to decay
