小知识
A molecule is the simplest structural unit of a substance that still keeps the properties of that substance, like a molecule of water. This scientific word also gets used in unscientific ways, as in “Every single molecule in my body wants that chocolate cupcake!”
People sometimes confuse molecules with atoms, but a molecule is made up of atoms. A molecule retains the characteristic of the substance it’s from, so a water molecule is still water. An atom only has the characteristics of its element, not the larger composition. For example, a water molecule, H2O, is made up of two hydrogen atoms and one oxygen atom.

particle，atom，grain，speck，molecule
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。
