What's the difference between a particle and a nano particle? what's their difference on a molecular level? PLEASE HELP ASAP !!!
I researched this a lot, but I still don't get it, for me they are the same, aren't all particles even smaller than the nano size? What makes a nano gold for example different than normal gold? Don't they have the same structure?
Why can't any particle observed on a nano scale be called a nano particle?
Then why are their such things such as nano silicon and such that have different behaviors then normal particles?
(you can answer in general)

It’s all semantics!
Explanation:
The term particle is completely broad and generic. It basically can apply to any physical object that exhibits a chemical or physical property, this means an atom can be considered a particle, an electron, a proton, even a molecule in certain situations. It’s a bit like saying a ‘house’. A house could be a mansion or equally a tiny log cabin.
A nanoparticle is referring to a particle sized particle (so to use the house example maybe a ‘three bedroomed detached house’). Usually nanoparticles are described as being between 100nm and 1nm in size.
Nanoparticles are of great interest because often nanoparticles of a given element behave differently to larger particles of a given element.
