Development of the Atomic Theory Democritus 460 BC Greek philosopher proposes the existence of the atom He pounded materials until he made them into smaller and smaller parts He called them . Physical Science. Chapter 4 – Section 2. State Standards. CLE.3202.1.2 – Describe the structure and arrangement of atomic particles. What is an Atom?. The three main components of an atom are . distinquished. Section 4.2. Objectives. State the three . subparticles. of atoms. State the charges of the . subparticles. Describe the composition of an atom. Atom. Fundamental particles which make up matter. The smallest particle of an element that retains (keeps) its identity in a chemical reaction. The Building Blocks of Matter. Chapter 2. Chapter Outline. 2.1 The . Rutherford Model of . Atomic Structure. 2.2. . Nuclides and Their Symbols. 2.3 . Navigating the Periodic Table. 2.4 The . Masses of Atoms, Ions, and Molecules. ASTR 101. Prof. Dave Hanes. The . Pessimist. [writing in 1835]. . On the subject of stars, all investigations which are not ultimately reducible to simple visual observations are…necessarily denied to us… We shall never be able by any means to study their chemical . Atoms, Orbitals & Bonding Topics:. Very quick history of chemistry…. What is organic chemistry?. Atomic models: nuclear to quantum. All . about . orbitals. How . orbitals fill: electron . configuration. Non metals and Metalloids. A non metal is an element that is not a metal and does not have properties of metals. A metalloid is an element that is not a metal but it is similar to a metal.. Physical properties of nonmetals: Most nonmetals are poor conductors of electric current and heat. Solid nonmetals tend to be dull and brittle.. . are the smallest components of nature. with the properties of a given substance.. Electrons. (negative charge). Protons. . (positive charge). Neutrons. . (no charge). For any given element:. Atomic Number . Darrick. Chang. ICFO – The Institute of Photonic . Sciences. Barcelona, Spain. School on Quantum Nano- and Opto-Mechanics. July 8, 2016. Motivation. Optomechanics: unprecedented levels of control over interactions between motion and light. There are about 100 different types of atoms. An element is a substance which contains only one type of atom. Atoms. Atoms. The Periodic Table. The Periodic Table. Element, Compound, Mixture. Element, Compound, Mixture. Matter and Atoms. Matter is anything that takes up space and has mass. There are 4 phases of matter solid, liquid, gas, and plasma.. All matter is made of atoms.. Atoms are the building blocks of matter, sort of how bricks are the building blocks of houses.. Essential Questions:. What is. . the basic structure of atoms? . How is an atom’s mass calculated? . Which subatomic particles are electrically charged?. .. Essential Questions:. 4. Where are the three main subatomic particles located?. The structure of atoms dictate their properties. How atoms combine dictate what we see in the many . minerals. in nature. . New technologies allow us to peer ever closer at the minute structures of minerals, down to the scale of individual atoms.. Examples:. Hydrogen. Carbon. Chlorine. Titanium. Atom. Democritus (450 B.C.). If . you kept cutting a substance in half forever, eventually you would end up with an “. uncuttable. ” particle. . John Dalton (1800). Develop and use models to illustrate the structure of atoms, including the subatomic particles with their relative positions and charges.. Date. Essential Question(s). 1) . What is matter?. 2) . What is the basic structure of atoms?.
