- Metallic element - A rare metallic element of the platinum group, found native
as an alloy in platinum ore, and in iridosmine. It is a hard,
infusible, bluish or grayish white metal, and the heaviest substance
known. Its tetroxide is used in histological experiments to stain
tissues. Symbol Os. Atomic weight 191.1. Specific gravity 22.477.
- 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.
- Blonde into heavy metal? - High-selling CD award - Jewellery metal - Precious metal - Sort of best-selling record for a blonde - Sort of bestselling record for a blonde - A metallic element, intermediate in value between silver
and gold, occurring native or alloyed with other metals, also as the
platinum arsenide (sperrylite). It is heavy tin-white metal which is
ductile and malleable, but very infusible, and characterized by its
resistance to strong chemical reagents. It is used for crucibles, for
stills for sulphuric acid, rarely for coin, and in the form of foil and
wire for many purposes. Specific gravity 21.5. Atomic weight 194.3.
Symbol Pt. Formerly called platina.
- Any statue of the goddess Pallas; esp., the famous
statue on the preservation of which depended the safety of ancient
Troy. - Hence: That which affords effectual protection or
security; a sateguard; as, the trial by jury is the palladium of our
civil rights. - A rare metallic element of the light platinum group,
found native, and also alloyed with platinum and gold. It is a
silver-white metal resembling platinum, and like it permanent and
untarnished in the air, but is more easily fusible. It is unique in its
power of occluding hydrogen, which it does to the extent of nearly a
thousand volumes, forming the alloy Pd2H. It is used for graduated
circles and verniers, for plating certain silver goods, and somewhat in
dentistry. It was so named in 1804 by Wollaston from the asteroid
Pallas, which was discovered in 1802. Symbol Pd. Atomic weight, 106.2.
