What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What is a beneficial aspect of nuclear fission?

Back

The ability to release tremendous amounts of energy.

Front

What is an alpha particle?

Back

An alpha particle is a type of nuclear radiation consisting of two protons and two neutrons, equivalent to a helium nucleus.

Front

What is nuclear waste?

Back

Nuclear waste is the radioactive byproduct of nuclear reactions, particularly from nuclear power plants, which poses disposal and environmental challenges.

Front

What type of radiation is emitted by an alpha particle?

Back

Alpha radiation.

Front

What is the mass number in isotope notation?

Back

The mass number is the top number in isotope notation, representing the total number of protons and neutrons in the nucleus.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, determining the element's identity.

Front

What is beta radiation?

Back

Beta radiation is a type of nuclear radiation that involves the emission of beta particles, which are high-energy, high-speed electrons or positrons.

Front

What is gamma radiation?

Back

Gamma radiation is a type of electromagnetic radiation emitted from the nucleus of an atom, characterized by high energy and no mass.

Front

What are the disadvantages of nuclear power?

Back

Disadvantages include nuclear waste, potential for accidents, and high costs of plant construction and decommissioning.
