这组词都有“粒,微粒”的意思,其区别是:
particle指任何物质的微粒,引申指任何小的部分。
atom指元素的最小粒子,其体积比molecule小。
grain通常指能为肉眼清楚看到的颗粒,比上述几个词所表“粒”的体积大。
speck一般指“微点”或“微粒”,可引申指“斑点、污点”。
molecule指物质中保持原物质的一切化学性质,能独立存在的最小微粒,即分子。

1794年,“极小的微粒”,源自17世纪的法语单词 molécule,源自现代拉丁语 molecula,是拉丁语 moles “团块, 障碍物”(参见 mole(n.3))的小型形式。见 -cule 以获取结尾。该词最初意思含糊; 这个词汇的流行(在18世纪末之前只用于拉丁形式)可以追溯到笛卡尔哲学。在现代科学意义上首次用于现代拉丁语 molecula(“物质可分离的最小部分,而不破坏其化学特性”),是由阿梅德奥·阿沃加德罗(Amedeo Avogadro)于1811年首次使用的。
分子:一种极小的物质块,或能独立存在的最小物质,由原子聚集而成,特别是二个以上原子结合的特种化合物
将其分解为组成的原子,可改变分子原有的特性
