William A Goddard III wagwagcaltechedu Charles and Mary Ferkel Professor of Chemistry Materials Science and Applied Physics California Institute of Technology 1 Lecture 6 and 7 April . Bell Ringer . Review..Frame. your argument. Bell Ringer: What was the name of the program to build the Atomic Bomb? Who was the lead scientist?. Agenda: Notes/discussion. Objective: Through Discussion and notes students will begin to understands the steps leading to the dropping of the atomic bomb.. #1: Rubidium has two common isotopes, . 85. Rb and . 87. Rb. . If the abundance of . 85. Rb is 72.2% and the abundance of . 87. Rb is 27.8%, what is the average atomic mass of rubidium?. PROCEDURE:. On your bell work . sheet, answer the following.. When . are zeros significant? . . When . do you use the fewest number of Significant Figures?. Objectives. The Structure of the Atom. Properties of Subatomic Particles. Yu-Shan . Lin (YSL).

The “sun” was the positively-charged dense nucleus and the negatively-charged electrons were the “planets”. Review & Introduction for Science 10. Vocabulary. ATOM. :. smallest particle of an element, has a neutral charge.. ELEMENT. :. made up of 1 type of atom (. eg. . Oxygen, . O. ). COMPOUND:. . a pure substance made up of 2 or more elements that are . 1. Unit Map. 2. You are here. 3. Facts and questions about organisms. Some things we know:. All organisms are made of cells. All the functions of organisms are done by cells working together. All cells are made of molecules. All atoms of an element have the same number of protons and the same atomic number.. Learning Goal . Given the atomic number and the mass number of an atom, state the number of protons, neutrons, and electrons.. GARRY KWAN YUAN. 23 AUGUST 2017. MSC THESIS PRESENTATION. 1. 01) WHAT ITS ALL ABOUT (some background knowledge). 02) THE GAME PLAN . 03) THE RESULTS (and some of the nitty-gritty). 04) WHAT DOES IT ALL MEAN. 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.. Dr. Julie Cohen. University of Virginia, Curry School of Education and Human Development. Overview. Why simulations?. The what and the how. An example study. Theory and methods. Possible implications. What are Atoms?. Atoms. are the building blocks of matter made up of Protons, Neutrons & Electrons.. Inside the Atom. A . proton. is a positively charged (+) particle in the center of the atom. Elements, Mixtures and Compounds. Atoms and molecules. Remember that an . element . is one type of atom, like carbon, gold or chlorine. We will look at three ways that atoms can exist.. 1. Single atoms.
