What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus, resulting in a change of one element into another.

What is the product of the beta decay of Carbon-14?

Back

The product of the beta decay of Carbon-14 (6^14C) is Nitrogen-14 (7^14N).

What process occurs naturally in the center of stars like the Sun?

Back

Fusion is the process that occurs naturally in the center of stars like the Sun, where hydrogen nuclei combine to form helium, releasing energy.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons), resulting in a new element.

What is the product of the alpha decay of Astatine-209?

Back

The product of the alpha decay of Astatine-209 (85^209At) is Bismuth-205 (83^205Bi).

Front

Order the types of radiation from most to least penetrating: Alpha, Beta, Gamma.

Back

Gamma, Beta, Alpha.

Front

What charge do beta particles have?

Back

Beta particles have a charge of -1.

Front

What is the definition of 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 the definition of nuclear fusion?

Back

Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is a neutron?

Back

A neutron is a subatomic particle found in the nucleus of an atom, with no electric charge and a mass slightly greater than that of a proton.
