2 They are 25 common elements e ssential to human life These elements a re also essential to other organisms What does this say about the similarity a mong organisms 3 What bond allows water to behave the way it does. 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?. Mallory . Traxler. April 2013. Motivation. Continuous atom laser. Continuous, coherent stream of atoms. Outcoupled. from a BEC. Applications of atom lasers:. Atom interferometry. Electromagnetic fields. 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. . Molecules. Elements. Compounds. Atom. The smallest particle that can still be identified as the matter it came from.. Atoms cannot be created or destroyed.. Consists of Protons (+), Electrons (-), and Neutrons (N).. 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. 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.). Atoms are composed of protons, neutrons and electrons. These subatomic particles are charged….. Atoms make elements… Elements can’t be broken down into anything simpler. . Examples:. Carbon= C. DO NOW:. 1. 2. 3. 4. The Greek Concept of . Atomos. : . The . Indivisible Atom. . Around 440 BC, Leucippus originated the atom concept.. His pupil, Democritus (c460-371 BC) extended it . There are five major points to their atomic idea.. Atoms and Isotopes. What you need to know about Atoms . and Isotopes:. Matter. Molecules. Elements. Chemical reaction. Periodic Table. The Atom. Parts of an atom. Isotopes. Unstable isotopes. Scientists and discoveries. Atom. An . atom. is the smallest particle of an . element. that retains the . chemical properties . of that . element. .. Atoms consist of . two. regions. The . nucleus. is at the . center. of the atom and contains at least one . Atoms and the Periodic Table Atomic Structure ATOM: the smallest particle that has the properties of an element. From the early Greek concept of the atom to the modern atomic theory, scientists have built on and modified existing models of the atom. Atoms are neutral. Protons = Electrons. There are special kinds of atoms..... Ions. Isotopes. Ions. An Ion is an atom that has gained or lost ELECTRONS, so it has an overall charge. If an atom gains electrons, it’s overall charge becomes negative. If an atom loses electrons, it’s overall charge becomes positive. . Tim Kovachy. Department of Physics and Astronomy and Center for Fundamental Physics (CFP), Northwestern University. CPAD 2021. Brief overview of atom interferometry. Enabling technology advances for large-area/long-baseline atom interferometry demonstrated with 10-meter baselines. Known as the “Laughing Philosopher”. “Nothing exists except atoms and empty space; everything else is opinion.”. Created term “. atomos. ” which literally means “not cut” or indivisible.
