G10 CW 2 T2 Radioactivity

What is nuclear decay?

• The process by which an unstable atomic nucleus loses energy by emitting radiation.

• The process by which an unstable atomic nucleus combines with another nucleus to form a larger nucleus.

• The process by which an unstable atomic nucleus splits into two smaller nuclei.

• The process by which an unstable atomic nucleus gains energy by absorbing radiation.

What are radioactive isotopes?

• Isotopes of an element with a stable nucleus that do not emit radiation.

• Isotopes of an element that do not emit radiation.

• Isotopes of an element with a stable nucleus that emit radiation as they decay.

• Isotopes of an element with an unstable nucleus that emit radiation as they decay.

What is alpha decay?

• Alpha decay is a type of radioactive decay in which an atomic nucleus emits a beta particle.

• Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle.

• Alpha decay is a type of radioactive decay in which an atomic nucleus emits a gamma particle.

• Alpha decay is a type of radioactive decay in which an atomic nucleus emits a neutron.

What is beta decay?

• Beta decay is a type of radioactive decay in which an alpha particle is emitted from an atomic nucleus.

• Beta decay is a type of radioactive decay in which a gamma ray is emitted from an atomic nucleus.

• Beta decay is a type of radioactive decay in which a beta particle (either an electron or a positron) is emitted from an atomic nucleus, resulting in the transformation of a neutron into a proton or a proton into a neutron.
