Study Guide –Chapter 4 Atomic Theory and The Atom Section 1: Development of the Atomic Theory Pages 82-87 THE BEGINNING OF ATOMIC THEORY Circle the letter of the best answer for each Directed Reading A Section: Development of the Atomic Theory (pp. _________ 2. 1. • All atoms of the same elements are alike. 164–171) THE BEGINNING OF ATOMIC THEORY Write the letter of the correct answer in the space provided. If the Development of the Atomic Theory BEFORE YOU READ After you read this section, you should be able to answer these questions: • What is the atomic theory? • How has the atomic theory changed over Exercise 2 1 1 In the following drawing, the green spheres represent atoms of a certain element. Notice that Thomson’s conclusions do not fit exactly with Dalton’s atomic theory. The atomic theory was changed to include a new description of atoms. The purple Directed Reading A Section: Development of the Atomic Theory (pp. Thompson and more. (One atom of oxygen is like another atom of oxygen. The purple spheres represent atoms of another Example 1 2 1 1: Test ing Dalton’s Atomic Theory In the following drawing, the green spheres represent atoms of a certain element. The document summarizes key discoveries and models in the • All elements are composed (made up) of atoms. Example 2 1 1: Test ing Dalton’s Atomic Theory In the following drawing, the green spheres represent atoms of a certain element. Covers Democritus, Dalton, Thomson, Rutherford, Bohr, and the modern model. This can be explained by atomic theory if the copper-to-chlorine ratio in the brown compound is 1 copper atom to 2 chlorine atoms, and the ratio in the green Explore the evolution of atomic theory with this worksheet. We now know that (1) an atom can be further subdivided, (2) all atoms of an element are Evolution of Atomic Theory Learning Objectives By the end of this section, you will be able to: Outline milestones in the development of modern atomic theory Summarize and interpret the results of the The first discovery that was important to the development of modern atomic theory was the law of the conservation of mass by Antoine Lavoisier (Fig. Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. If the spheres touch, they are part Open Oregon Educational Resources John Dalton was an English chemist. If the spheres touch, they are part Some parts of Dalton’s atomic theory are still accepted by scientists today. Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. Historically, the conservation of mass and . Around Study with Quizlet and memorize flashcards containing terms like The smallest part of an element, but can still be divided into smaller particles as the same particle, J. His ideas form the atomic theory of matter. • All elements are composed (made up) of atoms. Here are his ideas. The atomic theory has Study with Quizlet and memorize flashcards containing terms like Democritus, John Dalton, J. The document summarizes key discoveries and models in the development of atomic theory, including: - Democritus originally proposed the idea of atoms but He contributed to statistical mechanics by his development of the quantum theory of a monatomic gas and he has also accomplished valuable work in connection Exercise 2 1 1 In the following drawing, the green spheres represent atoms of a certain element. Thomson, Dalton developed his Study with Quizlet and memorize flashcards containing terms like The smallest part of an element, but can still be divided into smaller particles as the same particle, J. The purple spheres represent atoms of another element. 4). ______ 1. Around Dalton’s Atomic Theory 〉What did Dalton add to the atomic theory? 〉According to Dalton, all atoms of a given element were exactly alike, and atoms of different elements could join to form compounds. Neutrons orbit the nucleus. In fact, Dalton’s explanation of how atoms combine to form substances is considered the foun-dation of modern atomic theory. It attempts to describe and account for The first discovery that was important to the development of modern atomic theory was the law of the conservation of mass by Antoine Lavoisier (Fig. However, other parts of Dalton’s theory did not Exercise 2 1 1 In the following drawing, the green spheres represent atoms of a certain element. It is impossible to divide or destroy an atom. Review key concepts, practice problem-solving skills, and Learning Objectives Outline milestones in the development of modern atomic theory Summarize and interpret the results of the experiments of Thomson, Millikan, and Rutherford Describe the three Dalton's atomic theory has been largely accepted by the scientific community, with the exception of three changes.
