(chemistry only) Describe nanoparticles as structures of the order of a few hundred atoms.

In the subtopic Sizes of particles and their properties, this learning objective focuses on (chemistry only) Describe nanoparticles as structures of the order of a few hundred atoms. Within Bulk and surface properties of matter including nanoparticles (chemistry only), students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only, nanoparticle, and nano. nanoparticle means structures of the order of a few hundred atoms. Avoid students often describe nanoparticles as being made up of thousands of atoms instead of a few hundred; instead remember that nanoparticles are specifically defined as structures of the order of a few hundred atoms. For exam answers, remember that nanoparticles are typically made up of a few hundred atoms, which gives them unique properties compared to bulk materials.
