An unstable atom gives off its excess energy until it becomes stable.
不稳定的原子释放出多余的能量，直到变得稳定。
An unstable atom gives off its excess energy until it becomes stable. The energy emitted is radiation.
不稳定原子在达到稳定状态前，需要释放出自身多余的能量，这一能量即辐射。
The process by which an atom changes from an unstable state to a morestable state by emittingradiation is called radioactive decay or radioactivity.
这种原子通过释放射线从不稳定状态变到更加稳定的状态的过程被称为核衰减或放射。
The process by which an atom changes from an unstable state to a more stable state by emitting radiation is called radioactive decay or radioactivity.
原子通过辐射由不稳定状态转变为更加稳定状态的过程称为放射性衰变或放射性。
For example, the stabilizer of organotin compounds can be combined with the unstable chlorine atom of the carboxymethyl cellulose molecule, and the organotin and unstable chlorine atoms are replaced.
例如有机锡的稳定剂可以和羧甲基纤维素分子的不稳定氯原子配位结合，有机锡和不稳定的氯原子发生置换反应。
