  Element \El"e*ment\, n. [F. ['e]l['e]ment, L. elementum.]
     1. One of the simplest or essential parts or principles of
        which anything consists, or upon which the constitution or
        fundamental powers of anything are based.
        [1913 Webster]
  
     2. One of the ultimate, undecomposable constituents of any
        kind of matter. Specifically: (Chem.) A substance which
        cannot be decomposed into different kinds of matter by any
        means at present employed; as, the elements of water are
        oxygen and hydrogen.
        [1913 Webster]
  
     Note: The elements are naturally classified in several
           families or groups, as the group of the alkaline
           elements, the halogen group, and the like. They are
           roughly divided into two great classes, the metals, as
           sodium, calcium, etc., which form basic compounds, and
           the nonmetals or metalloids, as oxygen, sulphur,
           chlorine, which form acid compounds; but the
           distinction is only relative, and some, as arsenic,
           tin, aluminium, etc., form both acid and basic
           compounds. The essential fact regarding every element
           is its relative atomic number, which is equal to the
           number of protons in the nucleus, and also equal to the
           number of electrons in orbitals around the nucleus when
           the atom is neutral. When the elements are tabulated in
           the order of their ascending atomic numbers, the
           arrangement constitutes the series of the Periodic law
           of Mendelejeff. See Periodic law, under Periodic.
           This Periodic law enables us to predict the qualities
           of unknown elements. The number of elements known in
           1890 were about seventy-five, but at that time the gaps
           in the Periodic law indicated the possibility of many
           more. All of the elements up to atomic number 100 have
           now been observed though some are radioactive and very
           unstable, and in some cases cannot be accumulated in
           quantity sufficient to actually see by eye. The
           properties predicted by the periodic law wre close to
           the observed properties in many cases. Additional
           unstable elements of atomic number over 100 are
           observed from time to time, prepared in cyclotrons,
           particle acclerators, or nuclear reactors, and some of
           their properties are measurable by careful observation
           of microscopic quantities, as few as several atoms. For
           such unstable elements, the properties are now
           predicted primarily by calculations based on quantum
           mechanics. Such theories suggest that there may be an
           "island" of relative stability of elements of atomic
           number over 120, but this has yet to be confirmed by
           experiment.
           Many of the elements with which we are familiar, as
           hydrogen, carbon, iron, gold, etc., have been
           recognized, by means of spectrum analysis, in the sun
           and the fixed stars. The chemical elements are now
           known not be simple bodies, but only combinations of
           subatomic particles such as protons, neutrons, and
           electrons; ahd protons and neutrons are now believed to
           be themselves combinations of quarks, particles which
           are not observed singly, but only in combinations.
           In formulas, the elements are designated by
           abbreviations of their names in Latin or New Latin,
           given in the table below. The atomic weights given in
           the table below are the
  
     chemical atomic weights, in some cases being the weighted
        average of the atomic weights of individual isotopes, each
        having a different atomic weight. The atomic weight of the
        individual isotopes are called the physical atomic
        weights. In those few cases where there is only one stable
        isotope of an element, the chemical and physical atomic
        weights are the same. The mass-spectrometric atomic
        weights are those used for careful mass-spectrometric
        measurements. For more details about individual elements,
        see the element names in the vocabulary The Elements

     3. One of the ultimate parts which are variously combined in

            as synonymous with differential.
        (b) Sometimes a curve, or surface, or volume is considered

     10. One of the simple substances, as supposed by the ancient
         philosophers; one of the imaginary principles of matter.
         (a) The four elements were, air, earth, water, and fire;
  
     Note: whence it is said, water is the proper element of
           fishes; air is the element of birds. Hence, the state
           or sphere natural to anything or suited for its
           existence.
           [1913 Webster]
  
                 Of elements

From The Free On-line Dictionary of Computing (18 March 2015) :

  element
  
     1.  One of the items of data in an array.
  
     2.  One kind of node in an SGML, HTML, or
     XML document tree.  An SGML element is typically
     represented by a start tag ("

") and an end tag ("

"). In some SGML implementations, some tags are omissible, as with "

" in HTML. The start tag can contain attributes ("

"), which are an unordered set of key-value bindings for that element. Both the start tag and end tag for an element typically contain the "tag name" (also called the "{GI" or generic identifier) for that element. In XML, an element is always represented either by an explicit start tag and end tag, or by an empty element tag ' alt='a dodad' />"). Other kinds of SGML node are: a section of character data ("foo"), a comment (""), a markup declaration (""), or a processing instruction (""). (2001-01-30)
