整数法则
![](http://upload.wikimedia.org/wikipedia/commons/thumb/c/c6/Francis_William_Aston.jpg/220px-Francis_William_Aston.jpg)
在化学中,整数法则是指核素的质量是氢原子质量的整数倍[1]。
该法则是普洛特1815年所提假说的修改版本,其大意是任一原子的质量是氢原子质量的整数倍[2]。 整数法则也称为阿斯顿整数法则[3],以弗朗西斯·阿斯顿的名字命名。
弗朗西斯·阿斯顿因发现大量元素的非放射性同位素(通过质谱仪发现),以及对整数法则的阐述而荣获1922年诺贝尔化学奖[4]。
