Does An Unstable Nucleus Decay?

This decay, called spontaneous fission, happens when a large unstable nucleus spontaneously splits into two (or occasionally three) smaller daughter nuclei, and generally leads to the emission of gamma rays, neutrons, or other particles from those products.

How can you predict if the nucleus will be stable or unstable?

The principal factor for determining whether a nucleus is stable is the neutron to proton ratio. Elements with (Z<20) are lighter and these elements' nuclei and have a ratio of 1:1 and prefer to have the same amount of protons and neutrons.

Does an unstable nucleus undergoes radioactive decay?

Radioactive decay a the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments. … Every atom seeks to be as stable as possible. In the case of radioactive decay, instability occurs when there is an imbalance in the number of protons and neutrons in the atomic nucleus.
