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

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..

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

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

Nonmetallic :: Nonmetallic (a.) Not metallic.

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..

Nonmetallic :: Nonmetallic (a.) Resembling, or possessing the properties of, a nonmetal or metalloid; as, sulphur is a nonmetallic element..

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

Metallic :: Metallic (a.) Of, pertaining to, or characterized by, the essential and implied properties of a metal, as contrasted with a nonmetal or metalloid; basic; antacid; positive..

Silicon :: Silicon (n.) A nonmetalic element analogous to carbon. It always occurs combined in nature, and is artificially obtained in the free state, usually as a dark brown amorphous powder, or as a dark crystalline substance with a meetallic luster. Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust. Silicon is characteristically the element of the mineral kingdom, as carbon is of the organic world. Symbol Si. A

#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..

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..

Tantalum :: Tantalum (n.) 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..

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..

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..

Germanium :: Germanium (n.) A rare element, recently discovered (1885), in a silver ore (argyrodite) at Freiberg. It is a brittle, silver-white metal, chemically intermediate between the metals and nonmetals, resembles tin, and is in general identical with the predicted ekasilicon. Symbol Ge. Atomic weight 72.3..

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

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..

Zirconium :: Zirconium (n.) A rare element of the carbon-silicon group, intermediate between the metals and nonmetals, obtained from the mineral zircon as a dark sooty powder, or as a gray metallic crystalline substance. Symbol Zr. Atomic weight, 90.4..
