- Brittle Metallic Element - One of the elements; a metal of a reddish white color,
crystallizing in rhombohedrons. It is somewhat harder than lead, and
rather brittle; masses show broad cleavage surfaces when broken across.
It melts at 507¡ Fahr., being easily fused in the flame of a candle. It
is found in a native state, and as a constituent of some minerals.
Specific gravity 9.8. Atomic weight 207.5. Symbol Bi.
- A rare metallic element, of the same group as platinum,
which it much resembles, being silver-white, but harder, and brittle,
and indifferent to most corrosive agents. With the exception of osmium,
it is the heaviest substance known, its specific gravity being 22.4.
Symbol Ir. Atomic weight 192.5.
- Metallic element - Silvery-white element - A rare metallic element, discovered in certain ores of
zinc, by means of its characteristic spectrum of two indigo blue lines;
hence, its name. In appearance it resembles zinc, being white or lead
gray, soft, malleable and easily fusible, but in its chemical relation
it resembles aluminium or gallium. Symbol In. Atomic weight, 113.4.
- Metal, Ti - Metallic element - An elementary substance found combined in the minerals
manaccanite, rutile, sphene, etc., and isolated as an infusible
iron-gray amorphous powder, having a metallic luster. It burns when
heated in the air. Symbol Ti. Atomic weight 48.1.
- 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.
- Element with symbol Ba - Metallic element - Silvery-white element - Silvery-White Metallic Element - Soft silvery-white element - One of the elements, belonging to the alkaline earth group;
a metal having a silver-white color, and melting at a very high
temperature. It is difficult to obtain the pure metal, from the
facility with which it becomes oxidized in the air. Atomic weight, 137.
Symbol, Ba. Its oxide called baryta.
