PPT-Chapter 4: The Structure of the Atom

Atoms are the fundamental blocks of matter Chapter Big Idea Section 1 Early Ideas About Matter What are the similarities and differences of the atomic models of Democritus Aristotle and Dalton. A Look Into the Ultimate. ESSENTIAL QUESTIONS:. Why was an image of individual atoms considered such an important breakthrough?. How scientists discovered the component particles within atoms?. How can we possibly know anything about atomic structures?. (around 400 BCE). Democritus thought matter could be divided into. . smaller and smaller pieces until a . single indivisible . particle is reached. . He named this particle the . atom. He proposed that atoms are of different sizes, in constant motion, and separated by empty spaces.. Jon Coleman, Royal Society Research Fellow . To detect and measure effects of Dark Energy density or any dark contents of the vacuum (DCV) . 2. Many thanks to the support of the:. Liverpool Particle Physics Group. Atomos: Not to Be Cut. The History of . the Atom and the Atomic . Theory. Atomic Models. This model of the atom may look familiar to you. This is . the Bohr model. . In this model, the nucleus is orbited by electrons, which are in different energy levels. . What are the 3 major parts of an atom?. Proton . Neutron . Electron. Parts of an Atom. Another Model. SIMPLIFIED MODEL.. PROTON. Protons are positively charged particles found in the atomic nucleus. . Atoms. . are the smallest unit of matter. . Matter. . is anything that has mass and takes up space. . A . ball is matter, water is matter, even the air you breathe is matter!. What is an atom. ? (cont.). 4.1 Early Theories of .
