When a nucleus is unstable it has either too many or too few neutrons in the nucleus. This is what causes nuclear decay as the nucleus needs to have the correct ratio of neutrons to protons to be stable.
It may be triggered by an outside force, such as a colliding particle, or simply by chance.
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.
undergo radioactive decay, releasing alpha particles. This decay process results in the transformation of the radium 226 nucleus into a different element, typically radon 222, along with the release of energy.
Instability is due to a certain ratio between neutrons and protons in the atomic nucleus.
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.

An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
Too many or too few neutrons.
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
The process of a radioactive decay is atomic nucleus of an unstable atom loses energy by emitting ionizing particles
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.

Instability is due to a certain ratio between neutrons and protons in the atomic nucleus.
An unstable atom is an atom that has an imbalance in the ratio of protons to neutrons in its nucleus, making it prone to undergo radioactive decay. This decay results in the emission of particles or energy in order to achieve a more stable configuration. Unstable atoms will continue to decay until they reach a state of stability.
