normal atom meaning in Chinese

常态原子
正常原子

So in normal atoms with electrons in stationary states , the probability of the electron being within the nucleus ( or somewhere else in atom within similarly small volume ) is nearly zero according to the uncertainty principle ( it is nearly zero as the nucleus has a volume and is not a point )
因此在正常具有电子的原子里处于稳定状态，电子在核内的概率(或者处于原子里的某处类似小体积)是几乎为零按照测不准原理(它几乎为零如同核子具有体积而不是零那样) 。
