Chemistry Periodic Table of Elements Pen with Periodic Table Reference Sheet, Formulas, and Equations Perfect for Chemistry Study Tool, Chemistry Gift. The use of International Units and the expression of uncertainty in measurement is critical to all data activities. Provides access to all data sets at NIST. the use of the 2011 Edition Reference Tables for Physical Setting/Chemistry. It contains total energies and orbital energy eigenvalues for all atoms from hydrogen to uranium. Chemistry Reference Tables - Chemistry - 1 period periodic table of the elements ia 18 atomic ii 1s hydrogen english element name copper 2s lithium beryllium 6. 6 The elements on the Periodic Table of the Elements are arranged in order. This database consists of evaluated data for use in total-energy calculations of electronic structure by density-functional theory. This database calculates stopping-power and range tables for electrons, protons, or helium ions.Ĭontains a table of the half lives of 65 radionuclides and a database of the isotopic compositions, atomic weights and relative atomic masses of the elements. In addition, there are two publications containing equations and the underpinning theory for molecular spectroscopy.Ĭontains databases on thermophysical properties of gases, electron-impact cross sections (of atoms & molecules), potential energy surfaces of group II dimers, and atomic weights and isotopic compositions.Ĭontains databases on the interaction of x-rays and gamma-rays with elements and compounds. Includes databases containing spectroscopic data for small molecules, hydrocarbons, and interstellar molecules. Suitable for high-resolution color printing for desk or wall-chart display.Ĭontains values of the fundamental physical constants and a related bibliographic database.Ĭontains databases for energy levels, wavelengths, radiative transition probabilities, and ionization energies for atoms and ions and related bibliographic databases.
