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..

Nonmetallic :: Nonmetallic (a.) Not metallic.

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..

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

Veinstone :: Veinstone (n.) The nonmetalliferous mineral or rock material which accompanies the ores in a vein, as quartz, calcite, barite, fluor spar, etc.; -- called also veinstuff..

Electro-negative :: Electro-negative (a.) Negative; nonmetallic; acid; -- opposed to positive, metallic, or basic..

Anhydride :: Anhydride (n.) An oxide of a nonmetallic body or an organic radical, capable of forming an acid by uniting with the elements of water; -- so called because it may be formed from an acid by the abstraction of water..

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..

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..

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..

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

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

Phosphorus :: Phosphorus (n.) A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell. It is very active chemically, must be preserved under water, and unites with oxygen even at ordinary temperatures, giving a faint glow, -- whence its name. It always occurs compined, usually in phosphates, as in the mineral apatite, in bones, etc. It is used in the composition on the tips of friction matches, and for man

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

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

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

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..

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

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..
