question 194

Multiple Choice

The parallel concepts of the element and the atom constitute the very foundations of chemical science. An element is a substance that cannot be broken down into a simpler form capable of an independent existence as observable matter. As such, the concept of the element is a macroscopic one that relates to the world that we can observe with our senses. The atom is the microscopic realization of this concept. That is, it is the actual physical particle that is unique to each chemical element. Stephen Lower, Chem 1 Virtual Textbook
