  • Chemistry
  • Because scandium, yttrium, and lanthanum actually do not form compounds analogous to those of the other transition elements and because their chemistry is quite homologous to that of the lanthanoids, they are excluded from the present discussion of the main transition elements. (britannica.com)
  • reactions
  • Most inorganic chemical reactions fall into four broad categories: combination reactions, decomposition reactions, single displacement reactions, and double displacement reactions. (globalspec.com)
  • Lutetium usually occurs in association with the element yttrium [ citation needed ] and is sometimes used in metal alloys and as a catalyst in various chemical reactions. (rug.nl)
  • substances
  • Let us now look a bit more deeply into the nature of elements and compounds, which are collectively known as pure substances, so as to understand the minerals that are a subset of this larger grouping. (encyclopedia.com)
  • mineral
  • The fact that a mineral must be inorganic brings up another term that has a broader meaning in everyday life than in the world of science. (encyclopedia.com)
  • Chemically, a mineral must be of unvarying composition, a stipulation that effectively limits minerals to elements and compounds. (encyclopedia.com)
  • widely
  • These compounds are widely used in many applications, including electroplating, dye and precision casting, alcohol distillation, and papermaking. (globalspec.com)
  • properties
  • Solid State - diverse class of compounds that are solid at standard temperature and pressure, and exhibit unique properties as semiconductors, etc. (globalspec.com)
  • The magnetic properties of a coordination compound can provide indirect evidence of the orbital energy levels used in bonding. (britannica.com)
  • 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)
  • Elements
  • Without exception, the elements of the main transition series (i.e., excluding the lanthanoids and actinoids as specified below) form stable compounds in two or more formal oxidation states. (britannica.com)
  • tools
  • To reveal the apparatuses, chemicals, and tools, users simply tap the small circles displayed at the top of the screen. (genengnews.com)
  • General
  • Such a theory is the so-called ligand field theory (LFT), which has its origin in the more general, but more complicated, theory of chemical bonding called the molecular orbital (MO) theory. (britannica.com)
