Final answer:
The smallest uncharged individual unit of a compound is a molecule, which consists of atoms bonded together and exemplifies the compound's distinctive characteristics.
Step-by-step explanation:
The smallest uncharged individual unit of a compound is a molecule. A molecule is composed of two or more atoms that are held together by chemical bonds. For example, a water molecule is always made up of two hydrogen atoms and one oxygen atom, represented by the chemical formula H2O. In terms of scale, atoms are the smallest unit of an element that retains the unique properties of that element, with sizes around 100 picometers (1×10-10 m). Molecules are electrically neutral and illustrate the characteristic behavior of the compounds they make up.
