What happens in a nuclear decay?

When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation. You need to know the effect of alpha and beta decay on the nucleus.

Beside this, what is the definition of nuclear decay?

Radioactive decay (also known as nuclear decay or radioactivity) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, gamma ray, or electron

What are the four types of radioactive decay?

Altogether, there are three major types of nuclear decay that radioactive particles can undergo: alpha, beta, or gamma decay. Each type emits a particle from the nucleus. Alpha particles are high-energy helium nuclei containing 2 protons and 2 neutrons.
