Nonmetal :: Nonmetal (n.) Any one of the set of elements which, as contrasted with the metals, possess, produce, or receive, acid rather than basic properties; a metalloid; as, oxygen, sulphur, and chlorine are nonmetals..

Iodine :: Iodine (n.) A nonmetallic element, of the halogen group, occurring always in combination, as in the iodides. When isolated it is in the form of dark gray metallic scales, resembling plumbago, soft but brittle, and emitting a chlorinelike odor. Symbol I. Atomic weight 126.5. If heated, iodine volatilizes in beautiful violet vapors..

Tellurium :: Tellurium (n.) 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..

#NAME? :: -ide () 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..

Metalloid :: Metalloid (n.) Now, one of several elementary substances which in the free state are unlike metals, and whose compounds possess or produce acid, rather than basic, properties; a nonmetal; as, boron, carbon, phosphorus, nitrogen, oxygen, sulphur, chlorine, bromine, etc., are metalloids..

Negative :: Negative (a.) Metalloidal; nonmetallic; -- contracted with positive or basic; as, the nitro group is negative..

Non- :: Non- () A prefix used in the sense of not; un-; in-; as in nonattention, or non-attention, nonconformity, nonmetallic, nonsuit..

Spar :: Spar (n.) An old name for a nonmetallic mineral, usually cleavable and somewhat lustrous; as, calc spar, or calcite, fluor spar, etc. It was especially used in the case of the gangue minerals of a metalliferous vein..

Electro-positive :: Electro-positive (a.) Hence: Positive; metallic; basic; -- distinguished from negative, nonmetallic, or acid..

Tut-work :: Tut-work (n.) Work done by the piece, as in nonmetaliferous rock, the amount done being usually reckoned by the fathom..

Sulphur :: Sulphur (n.) 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..

Nonmetallic :: Nonmetallic (a.) Not metallic.

Nitrogen :: Nitrogen (n.) A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncon

Selenium :: Selenium (n.) A nonmetallic element of the sulphur group, and analogous to sulphur in its compounds. It is found in small quantities with sulphur and some sulphur ores, and obtained in the free state as a dark reddish powder or crystalline mass, or as a dark metallic-looking substance. It exhibits under the action of light a remarkable variation in electric conductivity, and is used in certain electric apparatus. Symbol Se. Atomic weight 78.9..

Antimony :: Antimony (n.) An elementary substance, resembling a metal in its appearance and physical properties, but in its chemical relations belonging to the class of nonmetallic substances. Atomic weight, 120. Symbol, Sb..

Blende :: Blende (n.) A general term for some minerals, chiefly metallic sulphides which have a somewhat brilliant but nonmetallic luster..

Arsenic :: Arsenic (n.) One of the elements, a solid substance resembling a metal in its physical properties, but in its chemical relations ranking with the nonmetals. It is of a steel-gray color and brilliant luster, though usually dull from tarnish. It is very brittle, and sublimes at 356¡ Fahrenheit. It is sometimes found native, but usually combined with silver, cobalt, nickel, iron, antimony, or sulphur. Orpiment and realgar are two of its sulphur compounds, the first of which is the true arsenicum of

Metalloid :: Metalloid (a.) Having the properties of a nonmetal; nonmetallic; acid; negative.

Metal :: Metal (n.) An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities, as chromium, manganese, bismuth, etc..

Boron :: Boron (n.) A nonmetallic element occurring abundantly in borax. It is reduced with difficulty to the free state, when it can be obtained in several different forms; viz., as a substance of a deep olive color, in a semimetallic form, and in colorless quadratic crystals similar to the diamond in hardness and other properties. It occurs in nature also in boracite, datolite, tourmaline, and some other minerals. Atomic weight 10.9. Symbol B..
