  • Atomic Spectra of Alkali Elements
    Atomic Spectra of Alkali Elements S. R. Kulkarni April 10, 2020 Rydberg primarily focused on studying the lines of alkali metals (Lithium, Potassium and Sodium).1 Rydberg organized the various features by their appearance on the pho- tographs:The alkali spectra were more complicated than that of hydrogen. Rydberg recog- nized that were three different types of lines: lines which looked \sharp" (on photographic plates), \principal" (strong lines that showed up in emission and absorption) and those which appeared ‘diffuse”. These series were abbreviated to S, P, D. Later \Fundamental" (F) was added. As noted earlier, Rydberg preferred to work with wavenumbers. Using data from Liveing and Deware he recast Angstrom's formula as follows: N k = k − (1) n 1 (n + µ)2 where kn is the wavenumber of the nth line in a given series. Rydberg kept N fixed to the value measured by Balmer with k1 µ being free parameters. Rydberg found the following formulae for Lithium R ks = ks − ; 2; 3; 4; ::: (2) n 1 (n + S)2 R kp = kp − 1; 2; 3; ::: (3) n 1 (n + P )2 R kd = kd − 2; 3; 4; ::: (4) n 1 (n + D)2 s −1 p −1 where S = 0:5951, P = 0:9596, D = 0:9974, k1 = 28601:6 cm k1 = 43487:7 cm , d −1 k1 = 28598:5 cm and we have switched to the modern notation in which N is replaced by R (the value he found was R = 109721:6 cm−1). Rydberg had confidence in the data that he was able to find a deeper connection between the constants between the series.

  • March 12Th CONTENT
    Issue 05, February 27th – March 12th CONTENT Introduction During the first two weeks of March we saw important alliances 1between car manufacturers for the development and supply of Batteries electric vehicles. Daimler AG will cooperate with BYD in China and Vehicles and Mitsubishi Motors will work with PSA Peugeot – Citroen in Europe. These announcements represent an important step BYD and Daimler will develop an for electrifying transportation; however going forward requires Electric Vehicle for the Chinese market many issues that still need to be solved. As a society we have Celgard announced expansion of assumed that it is “possible” to replace (in some way) oil for production capacity in Korea electricity, but the question is if we have figured out where and Misubishi Motors and PSA Peugeot how we could obtain this electricity. Once this issue is solved (at Citroen reached final agreement a “reasonable” price and in an environmental friendly way), Sanyo will supply a lithium ion battery the next step is the efficient distribution of this electricity. We system for traffic signals in Japan have seen some companies that are developing interesting business models, but we are far from a mass implementation. LG Chemical will build Volt battery Summarizing, the question that arises is: are we (as a society) plant in Michigan prepared for electrifying transportation? Regarding lithium, a key raw material for batteries used in electric vehicles, it is important to highlight that most of the projects that have been announced in the last years are in an early stage of development. Anyway, the trend is clear: in less than three years around 20 new Companies have announced more than 40 new lithium projects.

  • Helium Adsorption on Lithium Substrates
    JLowTempPhys DOI 10.1007/s10909-007-9516-5 Helium Adsorption on Lithium Substrates E. Van Cleve · P. Taborek · J.E. Rutledge Received: 25 July 2007 / Accepted: 13 September 2007 © Springer Science+Business Media 2007 Abstract We have developed a cryogenic pulsed laser deposition (PLD) system to deposit lithium films onto a quartz crystal microbalance (QCM) at 4 K. Adsorption isotherms of 4He on lithium were measured in the temperature range between 1.42 K and 2.5 K. The isotherms are qualitatively different from isotherms on strong sub- strates such as gold and weak substrates such as cesium. There is no evidence of the formation of solid-like layers of helium, and the helium coverage is approximately linear in the pressure over a wide range. By measuring the low coverage slope of the isotherms, the binding energy of helium to lithium was found to be approxi- mately −13.6 K. For lithium substrates less than approximately 100 layers thick, the chemical potential at which the superfluid transition was observed was surprisingly sensitive to the details of lithium deposition. Keywords Helium films · Pulsed laser deposition · Superfluidity · Alkali metal 1 Introduction When helium is adsorbed onto a strong heterogenous substrate such as gold, the first 2 or 3 statistical layers are solid-like. The nature of these layers is not yet clear, but the layers are amorphous and do not participate significantly in superflow at high coverages. Superfluidity on strong substrates requires a minimum critical coverage to saturate the solid-like layers, and the superfluid phase which forms at higher cover- ages flows over these layers and does not interact directly with the strong, short range This work was supported by NSF grant DMR 0509685.

  • Lithium Data Sheet
    98 LITHIUM (Data in metric tons of lithium content unless otherwise noted) Domestic Production and Use: The only lithium production in the United States was from a brine operation in Nevada. Two companies produced a wide range of downstream lithium compounds in the United States from domestic or imported lithium carbonate, lithium chloride, and lithium hydroxide. Domestic production data were withheld to avoid disclosing company proprietary data. Although lithium markets vary by location, global end-use markets are estimated as follows: batteries, 65%; ceramics and glass, 18%; lubricating greases, 5%; polymer production, 3%; continuous casting mold flux powders, 3%; air treatment, 1%; and other uses, 5%. Lithium consumption for batteries has increased significantly in recent years because rechargeable lithium batteries are used extensively in the growing market for portable electronic devices and increasingly are used in electric tools, electric vehicles, and grid storage applications. Lithium minerals were used directly as ore concentrates in ceramics and glass applications.

  • Molecular Orbital Theory to Predict Bond Order • to Apply Molecular Orbital Theory to the Diatomic Homonuclear Molecule from the Elements in the Second Period
    Skills to Develop • To use molecular orbital theory to predict bond order • To apply Molecular Orbital Theory to the diatomic homonuclear molecule from the elements in the second period. None of the approaches we have described so far can adequately explain why some compounds are colored and others are not, why some substances with unpaired electrons are stable, and why others are effective semiconductors. These approaches also cannot describe the nature of resonance. Such limitations led to the development of a new approach to bonding in which electrons are not viewed as being localized between the nuclei of bonded atoms but are instead delocalized throughout the entire molecule. Just as with the valence bond theory, the approach we are about to discuss is based on a quantum mechanical model. Previously, we described the electrons in isolated atoms as having certain spatial distributions, called orbitals, each with a particular orbital energy. Just as the positions and energies of electrons in atoms can be described in terms of atomic orbitals (AOs), the positions and energies of electrons in molecules can be described in terms of molecular orbitals (MOs) A particular spatial distribution of electrons in a molecule that is associated with a particular orbital energy.—a spatial distribution of electrons in a molecule that is associated with a particular orbital energy. As the name suggests, molecular orbitals are not localized on a single atom but extend over the entire molecule. Consequently, the molecular orbital approach, called molecular orbital theory is a delocalized approach to bonding. Although the molecular orbital theory is computationally demanding, the principles on which it is based are similar to those we used to determine electron configurations for atoms.

  • Introduction to Molecular Orbital Theory
    Chapter 2: Molecular Structure and Bonding Bonding Theories 1. VSEPR Theory 2. Valence Bond theory (with hybridization) 3. Molecular Orbital Theory ( with molecualr orbitals) To date, we have looked at three different theories of molecular boning. They are the VSEPR Theory (with Lewis Dot Structures), the Valence Bond theory (with hybridization) and Molecular Orbital Theory. A good theory should predict physical and chemical properties of the molecule such as shape, bond energy, bond length, and bond angles.Because arguments based on atomic orbitals focus on the bonds formed between valence electrons on an atom, they are often said to involve a valence-bond theory. The valence-bond model can't adequately explain the fact that some molecules contains two equivalent bonds with a bond order between that of a single bond and a double bond. The best it can do is suggest that these molecules are mixtures, or hybrids, of the two Lewis structures that can be written for these molecules. This problem, and many others, can be overcome by using a more sophisticated model of bonding based on molecular orbitals. Molecular orbital theory is more powerful than valence-bond theory because the orbitals reflect the geometry of the molecule to which they are applied. But this power carries a significant cost in terms of the ease with which the model can be visualized. One model does not describe all the properties of molecular bonds. Each model desribes a set of properties better than the others. The final test for any theory is experimental data. Introduction to Molecular Orbital Theory The Molecular Orbital Theory does a good job of predicting elctronic spectra and paramagnetism, when VSEPR and the V-B Theories don't.

    1469 The Canadian Mineralogist Vol. 43, pp. 1469-1487 (2005) BORATE MINERALS OF THE PENOBSQUIS AND MILLSTREAM DEPOSITS, SOUTHERN NEW BRUNSWICK, CANADA JOEL D. GRICE§, ROBERT A. GAULT AND JERRY VAN VELTHUIZEN† Research Division, Canadian Museum of Nature, P.O. Box 3443, Station D, Ottawa, Ontario K1P 6P4, Canada ABSTRACT The borate minerals found in two potash deposits, at Penobsquis and Millstream, Kings County, New Brunswick, are described in detail. These deposits are located in the Moncton Subbasin, which forms the eastern portion of the extensive Maritimes Basin. These marine evaporites consist of an early carbonate unit, followed by a sulfate, and fi nally, a salt unit. The borate assemblages occur in specifi c beds of halite and sylvite that were the last units to form in the evaporite sequence. Species identifi ed from drill-core sections include: boracite, brianroulstonite, chambersite, colemanite, congolite, danburite, hilgardite, howlite, hydroboracite, kurgantaite, penobsquisite, pringleite, ruitenbergite, strontioginorite, szaibélyite, trembathite, veatchite, volkovskite and walkerite. In addition, 41 non-borate species have been identifi ed, including magnesite, monohydrocalcite, sellaite, kieserite and fl uorite. The borate assemblages in the two deposits differ, and in each deposit, they vary stratigraphically. At Millstream, boracite is the most common borate in the sylvite + carnallite beds, with hilgardite in the lower halite strata. At Penobsquis, there is an upper unit of hilgardite + volkovskite + trembathite in halite and a lower unit of hydroboracite + volkov- skite + trembathite–congolite in halite–sylvite. At both deposits, values of the ratio of B isotopes [␦11B] range from 21.5 to 37.8‰ [21 analyses] and are consistent with a seawater source, without any need for a more exotic interpretation.
