What is nuclear chemistry?

The branch of chemistry that deals with the changes that occur in the nuclei of atoms.

What are isotopes?

Atoms of the same element that have different numbers of neutrons.

What is radioactive decay?

The spontaneous breakdown of an atomic nucleus resulting in the release of radiation.

What are alpha particles?

Particles consisting of two protons and two neutrons, emitted during radioactive decay.

What is beta decay?

The radioactive decay process in which a beta particle (an electron or positron) is emitted.

What is gamma radiation?

High-energy radiation emitted during radioactive decay.

What is half-life?

The time it takes for half of the nuclei in a radioactive sample to undergo radioactive decay.

What is nuclear fission?

The splitting of an atomic nucleus into two smaller nuclei, accompanied by the release of a large amount of energy.

What is nuclear fusion?

The combining of two atomic nuclei to produce a single heavier nucleus, accompanied by the release of a large amount of energy.

What are the uses of nuclear chemistry?

Nuclear power generation, medical imaging, cancer treatment, and dating archaeological artifacts.

What is a Geiger-Muller counter?

A device used to detect and measure ionizing radiation.

What is a radioactive tracer?

A small amount of a radioactive substance used to track the pathway of a substance within a living organism or system.

What is nuclear medicine?

The branch of medicine that uses radioactive isotopes to diagnose and treat diseases.

What is a nuclear reactor?

A device that initiates and controls a sustained nuclear chain reaction to generate heat or electricity.

What is nuclear waste?

The radioactive byproducts generated from nuclear power generation and other nuclear processes.
