Three of the most common types of decay are alpha decay (𝛼-decay), beta decay (𝛽-decay), and gamma decay (𝛾-decay), all of which involve emitting one or more particles. The weak force is the ...

Alpha decay causes the mass number of the nucleus ... An unstable nucleus can emit a fast-moving electron called a beta (β) particle, to become more stable. Beta radiation is made up of a stream ...
