First convert 0.163 grams of N2O to mol by dividing it with
the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer
would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one
mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.

Answer:
Atom
Explanation:
An atom is the smallest quantity of any given element.
An atom includes a nucleus (which includes protons and neutrons) around which are located the electrons. That's that specific assembly of nucleus and surrounding electrons that form an atom and define which element it is.
So,
electron: negative charge in orbit of the nucleus
proton: positively-charged particle inside the atomic nucleus
neutron: neutral particle inside the atomic nucleus
atom: ensemble of the nucleus and electrons, defining a given element.
