Radioactivity

The video tutorial explains the spontaneous decay of atomic nuclei, focusing on isotopes with unstable nuclei that decay into different isotopes and produce decay products. It covers three types of decay products: alpha particles, which are helium nuclei with low energy; beta particles, which are high-velocity electrons with more penetrating power; and gamma rays, which are high-energy photons with the highest energy levels.

What is the process by which unstable atomic nuclei change into different isotopes?

What are the three kinds of decay products that isotopes can emit?

Describe the characteristics of alpha particles.

What are beta particles and how do they differ from alpha particles?

Explain the nature of gamma rays and their energy compared to other decay products.
