THINK ABOUT IT – answer on your warm-up sheet or scratch paper. W. hat are the 3 main groups on the periodic table?. What are the 3 main parts of an atom?. You need to get . 3. different . color pencils. 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. Textbook Pages 4-5. Lesson Objectives. Appreciate that there are various models to illustrate atomic structure. Know that early models of atomic structure predicted that atoms and ions with noble gas electron arrangements should be stable. Advanced Chemistry. Ms. . Grobsky. Food For Thought. Rutherford’s model became known as the “planetary model”. The “sun” was the positively-charged dense nucleus and the negatively-charged electrons were the “planets”. Chapter 1D. Warm Up November . 28. What is smaller, an atom or a cell? . Name and describe one element that you are familiar with on the periodic table. . When large blooms of algae die, decomposers use all the oxygen in the water to break down the dead algae. What is this a result of? . The lab technician shown here is using a magnifying lens to examine a bacterial culture in a petri dish. When scientists cannot see the details of what they study, they try to obtain experimental data that help fill in the picture.. Science is based off of observations.. A Scientific Law is a summary of what is seen in observations. . A Scientific Theory is an explanation of why these observations are occurring.. Both laws and theories are tested by using them to predict what would happen in certain situations.. 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.. 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. Matter describes anything that has . mass. and . volume. Can matter be invisible? . YES. Ex. . Air. Matter and Atoms. History of atoms. Democritus. Was a . Greek. philosopher in . 400 BC. Thought the universe was made of . Chapter 1 Matter on the Atomic Scale Chemistry The science of matter and the transformations it can undergo. Consider the anticancer drug Taxol ® . Why should you study it? It helps us understand our surroundings and the way we function. Over the past century scientist have discovered that the atom is composed of 3 subatomic particles:. Protons. Neutrons. Electrons. Checking for understanding. Draw this diagram. Label all subatomic particles and include their charges.. Lundquist -- 2016. Properties of Matter. Unit 2.1. Describing Matter. Extensive. Dependent on amount. Mass. Volume. Weight. color. Intensive. Amount does not matter. Boiling point. Melting point. Density (. Daltons Atomic Theory. 1. All elements are composed of tiny . indivisible. particles called atoms.. 2. Atoms of the same element are identical. The atoms of one element are different from the atoms of another element..
