  • Neutron Stars
    Chandra X-Ray Observatory X-Ray Astronomy Field Guide Neutron Stars Ordinary matter, or the stuff we and everything around us is made of, consists largely of empty space. Even a rock is mostly empty space. This is because matter is made of atoms. An atom is a cloud of electrons orbiting around a nucleus composed of protons and neutrons. The nucleus contains more than 99.9 percent of the mass of an atom, yet it has a diameter of only 1/100,000 that of the electron cloud. The electrons themselves take up little space, but the pattern of their orbit defines the size of the atom, which is therefore 99.9999999999999% Chandra Image of Vela Pulsar open space! (NASA/PSU/G.Pavlov et al. What we perceive as painfully solid when we bump against a rock is really a hurly-burly of electrons moving through empty space so fast that we can't see—or feel—the emptiness. What would matter look like if it weren't empty, if we could crush the electron cloud down to the size of the nucleus? Suppose we could generate a force strong enough to crush all the emptiness out of a rock roughly the size of a football stadium. The rock would be squeezed down to the size of a grain of sand and would still weigh 4 million tons! Such extreme forces occur in nature when the central part of a massive star collapses to form a neutron star. The atoms are crushed completely, and the electrons are jammed inside the protons to form a star composed almost entirely of neutrons.

    CHEMISTRY EDUCATION: THE PRACTICE OF CHEMISTRY EDUCATION RESEARCH AND PRACTICE (PAPER) 2004, Vol. 5, No. 1, pp. 69-87 Concept teaching and learning/ History and philosophy of science (HPS) Juan QUÍLEZ IES José Ballester, Departamento de Física y Química, Valencia (Spain) A HISTORICAL APPROACH TO THE DEVELOPMENT OF CHEMICAL EQUILIBRIUM THROUGH THE EVOLUTION OF THE AFFINITY CONCEPT: SOME EDUCATIONAL SUGGESTIONS Received 20 September 2003; revised 11 February 2004; in final form/accepted 20 February 2004 ABSTRACT: Three basic ideas should be considered when teaching and learning chemical equilibrium: incomplete reaction, reversibility and dynamics. In this study, we concentrate on how these three ideas have eventually defined the chemical equilibrium concept. To this end, we analyse the contexts of scientific inquiry that have allowed the growth of chemical equilibrium from the first ideas of chemical affinity. At the beginning of the 18th century, chemists began the construction of different affinity tables, based on the concept of elective affinities. Berthollet reworked this idea, considering that the amount of the substances involved in a reaction was a key factor accounting for the chemical forces. Guldberg and Waage attempted to measure those forces, formulating the first affinity mathematical equations. Finally, the first ideas providing a molecular interpretation of the macroscopic properties of equilibrium reactions were presented. The historical approach of the first key ideas may serve as a basis for an appropriate sequencing of

  • This Ubiquitous Carbon…
    Engineering Physics Department Presents Dr. Cristian Contescu Senior Research Staff, Materials Science and Technology Division Oak Ridge National Laboratory This ubiquitous carbon… Abstract: After Stone Age, Bronze Age, and Iron Age, and after the Silicon Age of the informational revolution, the technologies of 21st century are marked by the ubiquitous presence of various forms of carbon allotropes. For a very long time, diamond and graphite were the only known carbon allotropes, but that has changed with the serendipitous discovery of fullerenes, carbon nanotubes, and graphene. Every ten or fifteen years scientists unveil new forms of carbons with new and perplexing properties, while computations suggest that the carbon’s family still has members unknown to us today. At a dramatically accelerated pace, new carbon forms find their place at the leading edge of scientific and technological innovations. At the same time traditional forms of carbon are being used in new and exciting applications that make our life safer, healthier, and more enjoyable. The 21st century may soon be recognized as the Age of Carbon forms. This educational talk will show how carbon, the fourth most abundant element in the Galaxy and the basis of life on Earth, was the engine of most important technological developments throughout the history of civilization. It will emphasize the ability of carbon atoms to generate a variety of mutual combinations and with many other chemical elements. These properties have placed carbon at the core of numerous inventions that define our civilization, while emerging new technologies open a rich path for value-added products in today’s market.

  • TEK 8.5C: Periodic Table
    Name: Teacher: Pd. Date: TEK 8.5C: Periodic Table TEK 8.5C: Interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements. Elements and the Periodic Table An element is a substance that cannot be separated into simpler substances by physical or chemical means. An element is already in its simplest form. The smallest piece of an element that still has the properties of that element is called an atom. An element is a pure substance, containing only one kind of atom. The Periodic Table of Elements is a list of all the elements that have been discovered and named, with each element listed in its own element square. Elements are represented on the Periodic Table by a one or two letter symbol, and its name, atomic number and atomic mass. The Periodic Table & Atomic Structure The elements are listed on the Periodic Table in atomic number order, starting at the upper left corner and then moving from the left to right and top to bottom, just as the words of a paragraph are read. The element’s atomic number is based on the number of protons in each atom of that element. In electrically neutral atoms, the atomic number also represents the number of electrons in each atom of that element. For example, the atomic number for neon (Ne) is 10, which means that each atom of neon has 10 protons and 10 electrons. Magnesium (Mg) has an atomic number of 12, which means it has 12 protons and 12 electrons.

  • Properties of Carbon the Atomic Element Carbon Has Very Diverse
    Properties of Carbon The atomic element carbon has very diverse physical and chemical properties due to the nature of its bonding and atomic arrangement. fig. 1 Allotropes of Carbon Some allotropes of carbon: (a) diamond, (b) graphite, (c) lonsdaleite, (d–f) fullerenes (C60, C540, C70), (g) amorphous carbon, and (h) carbon nanotube. Carbon has several allotropes, or different forms in which it can exist. These allotropes include graphite and diamond, whose properties span a range of extremes. Despite carbon's ability to make 4 bonds and its presence in many compounds, it is highly unreactive under normal conditions. Carbon exists in 2 main isotopes: 12C and 13C. There are many other known isotopes, but they tend to be short-lived and have extremely short half-lives. Allotropes The different forms of a chemical element. Cabon is the chemical element with the symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.

  • Centripetal Force Is Balanced by the Circular Motion of the Elctron Causing the Centrifugal Force
    STANDARD SC1 b. Construct an argument to support the claim that the proton (and not the neutron or electron) defines the element’s identity. c. Construct an explanation based on scientific evidence of the production of elements heavier than hydrogen by nuclear fusion. d. Construct an explanation that relates the relative abundance of isotopes of a particular element to the atomic mass of the element. First, we quickly review pre-requisite concepts One of the most curious observations with atoms is the fact that there are charged particles inside the atom and there is also constant spinning and Warm-up 1: List the name, charge, mass, and location of the three subatomic circling. How does atom remain stable under these conditions? Remember particles Opposite charges attract each other; Like charges repel each other. Your Particle Location Charge Mass in a.m.u. Task: Read the following information and consult with your teacher as STABILITY OF ATOMS needed, answer Warm-Up tasks 2 and 3 on Page 2. (3) Death spiral does not occur at all! This is because the centripetal force is balanced by the circular motion of the elctron causing the centrifugal force. The centrifugal force is the outward force from the center to the circumference of the circle. Electrons not only spin on their own axis, they are also in a constant circular motion around the nucleus. Despite this terrific movement, electrons are very stable. The stability of electrons mainly comes from the electrostatic forces of attraction between the nucleus and the electrons. The electrostatic forces are also known as Coulombic Forces of Attraction.
