Particles同molecules有咩分別??

"Particles" can mean atoms , molecules , ionic substance . When we say Avagado's # stated that there are 6x10^23 particles for 1 mol of substances . The particle is a general term .
For " Sub-atomic Particles " which refers to Proton , Electron & Neutron . There are other meanings for Particle for non-sceitific explanations .
Molecule is a group of 2 atoms or more held together by covalent bonds e .g.CO2 or N2 .

particles 泛指粒子(包括molecles, ions等等),化學上沒有特別說明什么結构的意思
molecules 指由covalent band組成的粒子(分子),如 O2(氧氣) H2O(水) CO2(二氧化碳)等等

如果係科學角度講的話就有分別!!

particles係中文首先係解粒子(我諗你都知)

molecules係中文係解分子

粒子係一個物質上最最最細少的單位
(e.g hydrogen 氫 , oxygen 氧 = 元素 elements)

而分子係要由多粒粒子所組成(e.g 多個元素組成 water 水 由氫氣同氧氣組成)

我諗你會明的= =
