Types of Nuclear Decay

Why does Alpha decay occur?

It occurs when the nucleus is too large and has too many nucleons, so it ejects some excess nucleons.

What transformation occurs in Alpha decay?

An unstable nucleus forms a new element by emitting an alpha particle.

Why does Beta decay occur?

It occurs when you have an unbalanced amount of protons and neutrons.

What transformation occurs in Beta decay?

An unstable atomic nucleus transforms by converting a neutron into a proton or vice versa, resulting in a different element.

Why does Gamma decay occur?

When the nuclei are in an excited state and need to eject excess energy.

What transformation occurs in Gamma decay?

An unstable atomic nucleus releases excess energy by emitting gamma rays. This does not change the identity of the atom.
