Respuesta :
Nuclear decay results in the change in the mass number of a nucleus. In precise it is alpha decay.
What is nuclear decay?
The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration.
What is alpha decay?
- A nuclear process known as "alpha decay" releases a particle made up of two protons and two neutrons when an unstable nucleus transforms to another element.
- The helium nucleus that is being ejected is known as an alpha particle.
- Positive charge and a sizable mass characterize alpha particles.
How is mass number of nucleus is changed by alpha decay?
When a nucleus emits an alpha particle, these changes happen:
- the mass number decreases by 4.
- the atomic number decreases by 2.
