Atomic massIsotopesOrganic compoundsNumerical parameters of stable and long-lived radioactive isotopes whose half-lives are longer than that of the neutron, are examined. Results are collected for the isotopic composition and atomic weights of the elements, the spins and magnetic moments of nuclei, ...
1. We have investigated their formation enthalpies upon alloying into hcp-Fe at high pressures. Furthermore, we have also included additional elements which are not volatile, such as P and Ge, as shown in Table S1 and Fig. S1, to investigate their possible alloying propensity with Fe at ...

ATOMIC WEIGHTS OF THE ELEMENTS 2007 These tables are based on the 2007 table at Pure Appl. Chem., 81, 2131-2156 (2009) with changes to the values for lutetium, molybdenum, nickel, ytterbium and zinc from the 2005 table. Mass number of the longest-lived isotope of hassium from Phys. Rev...
The elements of the periodic system with names, symbols, atomic numbers and weights, melting and boiling points, density, electronegativity and electron affinity, and electron configuration.
Density functional theory is an alternative to wave function-based methods using approximate functionals of the one-particle densities and currents. Electron correlation The difference between an atomic or molecular property evaluated with a single determinant at the Dirac–Hartree–Fock level and the sam...
electronconfiguration[Ar]4s23d1. Through the next nine elements, in increasing order of atomic number, electrons are added to the 3dorbitals until, at the element zinc, they are entirely filled and the electron configuration is [Ar]3d104s2. The 4porbitals are then the ones of lowest energy...
