Question

An unstable nucleus spontaneously releases a positron. this is an example of

Answer 1

The scenario in which an unstable nucleus spontaneously releases a positron is an example of radiation.
Radioactive is any unstable nucleus that spontaneously emits small particles of energy called radiation to become more stable.
Alpha particle, beta particle, position, gamma ray, proton and neutron are different types of radiation.

Answer 2

An unstable nucleus spontaneously releases a positron. This is an example of radiation.

Further Explanation:

Radiations are the emission of energy in the structure of waves. There is a different type of radiations such as:

• Electromagnetic radiation
• Particle radiation
• Acoustic radiation
• Gravitational radiation

Radioactive decay is a reaction by which an unstable nucleus of an atom loses energy by releasing radiation and converts into a stable nucleus. Three types of particle are:

• Alpha particle
• Beta particle
• Gamma particle

Examples of positrons are alpha and beta particles. Alpha decay is a nuclear process in which alpha particles are released. In beta decay, a beta particle is released from the nucleus.

Beta-decay is two types:

• β-  decay
• β+ decay

In β- decay, the nucleus has a high level of the neutrons which then converted into electron neutrino, electron, and proton. In β+ decay, the nucleus has a high level of protons which then converted into a positron, electron neutrino, and neutron. β-particle is a very high ionizing particle which is hazardous to living tissue.
