How are colors created by atoms
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. WebA box of ball-and-stick model pieces colored to represent several of the common elements. Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound.
