拉塞福模型 Rutherford model

(重定向自Planetary Model)
锂原子的拉塞福模型,经过美工处理后的示意图

拉塞福模型,或太阳系模型,是物理大师欧尼斯特·拉塞福创立的原子模型。1909年,拉塞福领导设计与发展成功的拉塞福散射,证实了原子核存在于原子中心处。从此,拉塞福推翻了约瑟夫·汤姆孙主张的梅子布丁模型。拉塞福设计的新模型,根据他的实验结果,拥有几个重要的特色。大多数的质量和正电荷,都集中于一个很小的区域(原子核);电子则环绕在原子核的外面,像行星的环绕着太阳进行公转。

The Rutherford model is a model of the atom devised by Ernest Rutherford. Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's so-called "plum pudding model" of the atom was incorrect. Rutherford's new model for the atom, based on the experimental results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom. This region would be known as the "nucleus" of the atom.
