Some nuclei, especially heavier ones, are unstable , or radioactive, emitting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Some nuclei, especially heavier ones, are unstable, or radioactive, emit ting energy in the form of alpha rays, beta rays, or gamma rays.
