What particle is emitted during beta decay?

Back

A beta particle is emitted during beta decay.

Front

What type of nuclear radiation is an alpha particle?

Back

Alpha radiation consists of alpha particles, which are made up of 2 protons and 2 neutrons.

Front

What happens during positron emission?

Back

During positron emission, a proton changes into a neutron.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which unstable atomic nuclei lose energy by emitting radiation.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, releasing energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy.

Front

What is gamma radiation?

Back

Gamma radiation is a type of high-energy electromagnetic radiation emitted from a radioactive nucleus.

Front

What is the charge of a beta particle?

Back

A beta particle can have a charge of -1 (beta minus) or +1 (beta plus, positron).

Front

What is an alpha particle composed of?

Back

An alpha particle is composed of 2 protons and 2 neutrons.
