Lecture #2, Periodic Table, Atomic Structure Welcome to 3.091 Lecture 2 September 11, 2009 The Periodic Table Public domain image from Wikimedia. John Dalton 1803 Public domain image from Wikimedia. Dalton’s Model of the Atom (1803) 1. Matter is composed of atoms that are indivisible and indestructible. 2. All atoms of an element are identical. 3. Atoms of different elements have different weights and different chemical properties. 4. Atoms of different elements combine in simple whole number ratios to form compounds. 5. Atoms cannot be created or destroyed. When a compound is decomposed, the atoms are recovered unchanged. 1869 H He Li Be B C N O Na Mg Al Si P S Cl K Ca Ti V Cr Mn Fe Co Ni Cu Zn As Se Br Rb Sr Y Zr Nb Mo Ru Rh Pd Ag Cd In Sn Sb Te I Cs Ba Ta W Os Ir Pt Au Hg Tl Pb Bi La Ce Tb Er Th U Image by MIT OpenCourseWare. 1869 Image by MIT OpenCourseWare. principles of modern chemistry: * recognize patterns * develop a quantitative model that -

  • Dirac-Exact Relativistic Methods: the Normalized Elimination of the Small Component Method† Dieter Cremer,∗ Wenli Zou and Michael Filatov
    Advanced Review Dirac-exact relativistic methods: the normalized elimination of the small component method† Dieter Cremer,∗ Wenli Zou and Michael Filatov Dirac-exact relativistic methods, i.e., 2- or 1-component methods which exactly reproduce the one-electron energies of the original 4-component Dirac method, have established a standard for reliable relativistic quantum chemical calculations targeting medium- and large-sized molecules. Their development was initiated and facilitated in the late 1990s by Dyall’s development of the normalized elimination of the small component (NESC). Dyall’s work has fostered the conversion of NESC and related (later developed) methods into routinely used, multipurpose Dirac- exact methods by which energies, first-order, and second-order properties can be calculated at computational costs, which are only slightly higher than those of nonrelativistic methods. This review summarizes the development of a generally applicable 1-component NESC algorithm leading to the calculation of reliable energies, geometries, electron density distributions, electric moments, electric field gradients, hyperfine structure constants, contact densities and Mossbauer¨ isomer shifts, nuclear quadrupole coupling constants, vibrational frequencies, infrared intensities, and static electric dipole polarizabilities. In addition, the derivation and computational possibilities of 2-component NESC methods are discussed and their use for the calculation of spin-orbit coupling (SOC) effects in connection with spin-orbit splittings and SOC-corrected

The 2cNESC is a Dirac-exact method that employs the exact two- component one-electron Hamiltonian and thus leads to exact Dirac SO splittings for one-electron atoms. For many-electron atoms and molecules, the effect of the two-electron SO interaction is mod- eled by a screened nucleus potential using effective nuclear charges as proposed by Boettger [Phys. Rev. B 62, 7809 (2000)]. The use of the screened nucleus potential for the two-electron SO inter- action leads to accurate spinor energy splittings, for which the deviations from the accurate Dirac Fock-Coulomb values are on the average far below the deviations observed for other effective one- electron SO operators.

CHATT University of Sussex, U.K. PERGAMON PRESS OXFORD · NEWYORK · PARIS . FRANKFURT Inorganic Chemistry Division Cornmission on the Nomenclature of Inorganic Chemistry* RECOMNENDATIONS FOR THE NAHING OF ELEHENTS OF ATOHIC NUHBERS GREATER THAN 100 (Rules Approved 1978) Elements of atomic numbers of 101 to 103 have trivial names and corresponding two letter symbols approved by IUPAC. The status of these names and symbols is in no way affected by the recommendation of systematic names for elements of atomic numbers greater than 100. Elements of atomic numbers greater than 103 are often referred to in the scientific literature but receive names only after they have been 'discovered'. Names are needed for indexing and other purposes and the Commission on Nomenclature of Inorganic Chemistry was asked to make recommendations concerning names and symbols of the heavy 'unknown' elements. The Ceromission decided that these elements would be best named systematically and that names should aceerd with the following principles: (i) The names should be short and obviously related to the atomic numbers of the elements. (ii) The names should end in 'ium' whether the elementwas expected to be a metal or otherwise. (iii) The symbols for the systematically named elements should consist of three letters.

  • Short Notes on Periodic Table Modern Periodic Table: Earlier Scientists
    Short Notes on Periodic Table Modern Periodic Table: Earlier scientists assumed that the properties of elements are periodic functions of their atomic masses. On the basis of this assumption, Mendeleev placed 63 elements in a vertical column called groups and in horizontal rows called periods. This method was rejected as it could not explain the position of certain elements, rare earth metals, and isotopes. A scientist named Henry Moseley removed these defects and put forward the modern periodic table with the modern periodic law. Moseleys Periodic Law: He stated that the properties of elements are periodic functions of their atomic number. Modern Periodic Table: A tabular arrangement of elements in groups and periods which highlights the regular trends in properties of elements is defined as the periodic table. Features of Modern Periodic Table There are eighteen vertical columns known as groups in the modern periodic table which are arranged from left to right and seven horizontal rows which are known as periods. Group number Group name Property Group 1 or IA Alkali metals They form strong alkalis with water Group 2 or IIA Alkaline earth They also form alkalis but weaker than group 1 elements metals Group 13 or IIIA Boron family Boron is the first member of this family Group 14 or IVA Carbon family Carbon is the first member of this property Group 15 or VA Nitrogen family This group has non-metals and metalloids Group 16 or VIA Oxygen family They are also known as chalcogens Group 17 or Halogen family The elements of this group form salts.

  • The Race for New Chemical Elements
    COVER STORY Periodic Table of the Elements Dmitri Ivanovich Mendeleev (https://www.sciencephoto.com) To celebrate the 150th anniversary of the Periodic Table of elements, The Race for the United Nations has proclaimed 2019 as the International Year of the Periodic Table. However, New Chemical scientists claim that the Periodic Table is far from being complete. And an interesting race is on Elements worldwide to synthesise new elements. Ramesh Chandra Parida 14 | Science Reporter | May 2019 YSTEMATISATION is an essential part of the scientific Table 1. List of man-made elements, their symbols and the knowledge that makes the study of science easier and year of discovery Sguides it into the future. Many eminent scientists have made their epoch-making contributions to achieve it in various Atomic Year of fields of science. Undoubtedly one of the foremost among number Name Symbol discovery them is the Russian Chemist Dmitri Ivanovich Mendeleev, who designed the “Periodic Table of Elements” a century and 93 Neptunium Np 1940 half ago (on 17 February 1869) making the study of chemistry 94 Plutonium Pu 1940-41 systematic. 95 Americium Am 1944-45 In fact, the process began with Dobeveiner. He classified certain elements with similar properties into groups of three, 96 Curium Cm 1944 called triads. Then Newland (1863) observed that if the elements 97 Berkelium Bk 1949 are arranged in the order of their atomic weights, the 8th element starting from a given one is a kind of repetition of the first, 98 Californium Cf 1950 like the 8th note of music and he called it the Law of Octaves.
