  • Solids
  • Elements of equilibrium statistical thermodynamics for classical and quantum mechanical systems, with applications to ideal gases, crystalline solids, imperfect gases and liquids. (dartmouth.edu)
  • complexes
  • Inorganic spectroscopy (e.g. magnetic susceptibility, EPR, electronic absorption, vibrational, resonance Raman, magnetic circular dichroism, photoelectron, X-ray absorption and EXAFS, paramagnetic NMR) and ligand field and molecular orbital theories of transition metal complexes. (stanford.edu)
  • periods
  • They occupy the middle portions of the long periods of the periodic table of elements (see Figure ) between the groups on the left-hand side and the groups on the right. (britannica.com)
  • atomic
  • While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated. (britannica.com)
  • The first of the inner transition series includes the elements from cerium (symbol Ce, atomic number 58) to lutetium (symbol Lu, atomic number 71). (britannica.com)
  • The actinoid series consists of 15 elements from actinium (symbol Ac, atomic number 89) to lawrencium (symbol Lr, atomic number 103). (britannica.com)
  • In the periodic table, the elements are represented by an atomic symbol, atomic number and atomic mass. (reference.com)
  • The choice of the elements selected to form these triads was made on account of their analogous properties, and on the sequence of their atomic weights, which had at that time only recently been discovered. (lemoyne.edu)
  • and the atomic weight of strontium, 42.5, is the arithmetical mean of those of the other two elements, for (65+20)/2 = 42.5. (lemoyne.edu)
  • Another method of classifying the elements, also depending on their atomic weights, was suggested by Pettenkofer, and afterwards elaborated by Kremers, Gladstone, and Cook. (lemoyne.edu)
  • It consisted in seeking for some expression which would represent the differences between the atomic weights of certain allied elements. (lemoyne.edu)
  • The upshot of these efforts to discover regularity was that in 1864, Mr. John Newlands, having arranged the elements in eight groups, found that when placed in the order of their atomic weights, "the eighth element, starting from a given one, is a kind of repetition of the first, like the eighth note of an octave in music. (lemoyne.edu)
  • copper
  • Copper is by far the most heavily used of these elements due to its electrical properties, its commonness (contrasted to silver and gold) and the attractiveness of its alloys brass and bronze. (wikibooks.org)
  • second
  • The second definition is commonly considered to exclude Zn, Cd and Hg because these elements have a d 10 electronic configuration (the d-orbitals being fully, not partially, occupied). (wikibooks.org)
  • known
  • To select a name expressible by a symbol which has not already been claimed for one of the known elements is difficult, and the difficulty is enhanced when it is at the same time required to select a name which shall be descriptive of the properties (or want of properties) of the element. (lemoyne.edu)
  • silver
  • Third, most of these elements dissolve in mineral acids, although a few, such as platinum , silver , and gold , are called "noble"-that is, are unaffected by simple (nonoxidizing) acids. (britannica.com)
