Webion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations ; negatively charged ions, anions . WebEven if we can't see atoms with our naked eye, properties of matter such as color, phase (e.g., solid, liquid, gas), and even smell come from interactions on an atomic level. This article will discuss John Dalton's atomic theory, which was the first complete attempt to describe all matter in terms of atoms and their properties.
