- Chemical element - Element that makes up diamonds - Element with symbol C - Non metallic element - Non-metallic element - Nonmetallic element - An elementary substance, not metallic in its nature, which
is present in all organic compounds. Atomic weight 11.97. Symbol C. it
is combustible, and forms the base of lampblack and charcoal, and
enters largely into mineral coals. In its pure crystallized state it
constitutes the diamond, the hardest of known substances, occuring in
monometric crystals like the octahedron, etc. Another modification is
graphite, or blacklead, and in this it is soft, and occurs in hexagonal
prisms or tables. When united with oxygen it forms carbon dioxide,
commonly called carbonic acid, or carbonic oxide, according to the
proportions of the oxygen; when united with hydrogen, it forms various
compounds called hydrocarbons. Compare Diamond, and Graphite.
- Rare metallic element - A rare nonmetallic element found in certain minerals, as
tantalite, samarskite, and fergusonite, and isolated as a dark powder
which becomes steel-gray by burnishing. Symbol Ta. Atomic weight 182.0.
Formerly called also tantalium.
- A suffix used to denote: (a) The nonmetallic, or negative,
element or radical in a binary compound; as, oxide, sulphide, chloride.
(b) A compound which is an anhydride; as, glycolide, phthalide. (c) Any
one of a series of derivatives; as, indogenide, glucoside, etc.
- A rare nonmetallic element, analogous to sulphur and
selenium, occasionally found native as a substance of a silver-white
metallic luster, but usually combined with metals, as with gold and
silver in the mineral sylvanite, with mercury in Coloradoite, etc.
Symbol Te. Atomic weight 125.2.
- brimstone - Non metallic element - A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as pyrites) and
sulphates (as gypsum), or native in volcanic regions, in vast beds
mixed with gypsum and various earthy materials, from which it is melted
out. Symbol S. Atomic weight 32. The specific gravity of ordinary
octohedral sulphur is 2.05; of prismatic sulphur, 1.96. - Any one of numerous species of yellow or orange
butterflies of the subfamily Pierinae; as, the clouded sulphur
(Eurymus, / Colias, philodice), which is the common yellow butterfly of
the Eastern United States.
