Nuclear Decay

What is nuclear chemistry

• Nuclear chemistry is the study of chemical reactions in nuclear power plants
• Nuclear chemistry focuses on the study of chemical reactions in living organisms
• Nuclear chemistry is the subfield of chemistry that deals with changes in the nucleus of atoms, including nuclear reactions and radioactive decay.
• Nuclear chemistry involves the study of chemical reactions in outer space

Describe radioactive decay.

• Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.
• Radioactive decay is a reversible process in nature.
• Radioactive decay involves the stabilization of atomic nuclei.

What are radioactive isotopes?

• Isotopes that do not decay
• Isotopes with a stable nucleus
• Isotopes that emit light instead of radiation
• Isotopes with excess nuclear energy, making them unstable and more likely to decay.

What is radiation?

• Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
• Radiation is the absorption of energy by subatomic particles
• Radiation is the release of energy through chemical reactions
