A. 400 B.C. –Democritus. 1. Defined nature’s basic particles as . atoms. a. means indivisible. B. 350 B.C. Aristotle. 1. said matter was made of the 4 “elements”. Chapter 3. Types of Models – Why do we use models?. Physical Model vs. Conceptual Model. Physical model. is a representation of a very large or small object shown at a convenient scale. . Mrs. Medina. 1. Why do metals glow when heated?. 2. Models of the Atom. A model should explain not just what the material is made of (composition) but also how it is going to behave (changes).. Rutheford’s.

His ideas were not useful in explaining chemical behavior because . What is Today’s Model?. Dense, Positively Charged Nucleus. Mostly. Empty. Space. Negatively Charged. Electron Cloud. Most Probable Location of the Electrons. Composed of Protons, Neutrons, and Electrons. FDR receives a letter from Albert Einstein. Informed FDR of recent developments in splitting uranium atoms. Could lead to “extremely powerful bombs of a new type” by means of nuclear fission. Nucleus absorbs a neutron, breaks into two equal fragments. How and why has the Atomic Theory changed over time? . How can we describe the molecular motion of the states of matter? . Objectives. Students will explain that atoms are the smallest unit of an element and are composed of subatomic particles..
