Bismuth is
a high-density
, silvery, pink-tinged metal. Bismuth metal is brittle and so it is usually mixed with other metals to make it useful. Its alloys with tin or cadmium have low melting points and are used in fire detectors and extinguishers, electric fuses and solders.
What is bismuth density?
The density of liquid bismuth is
10·022 g/cm
3
at its melting point
and 8·498 g/cm
3
at its normal boiling point
Is bismuth a heavy metal?
Elemental bismuth occurs as metallic crystals associated with nickel, cobalt, silver, tin, and uranium sulphide ores. Number 83 on the periodic table, it is mainly a byproduct of lead ore processing; yet among the heavy metals,
it is the heaviest and the only non-toxic
.
Is bismuth denser than water?
Elemental
bismuth is denser in the liquid phase than the solid
, a characteristic it shares with germanium, silicon, gallium, and water.
Is bismuth hard or soft?
Bismuth is
a hard, brittle metal
that grows in staircase-shaped crystals (Fig. 1) due to a greater growth rate on its outside edges than on the inside. It is a dull, silvery-white color but becomes slightly pink after surface oxidation occurs.
Why bismuth is not toxic?
Of the heavy metals including lead, mercury, arsenic, and bismuth, it is the latter whose salts are relatively the least toxic. This is probably
because of the great insolubility of many bismuth salts that prevents their absorption
.
Is bismuth toxic to humans?
In the clinic, depending on the administration time of bismuth,
its toxicity can be roughly divided into acute and chronic exposures
. Both exposure doses can cause neurotoxicity, gastrointestinal toxicity, nephrotoxicity, hepatotoxicity, and increased bismuth concentration in blood.
What is the heaviest liquid on Earth?
Mercury
is the densest liquid at standard conditions for temperature and pressure (STP). Also called quicksilver, mercury has been known for more than 3,500 years. It is an important metal in industry, but it is also toxic.
What is bismuth used for today?
Bismuth is a brittle, crystalline, white metal with a slight pink tinge. It has a variety of uses, including
cosmetics, alloys, fire extinguishers and ammunition
. … It also has a particularly low melting point, which enables it to form alloys that can be used for molds, fire detectors and fire extinguishers.
Is bismuth expensive?
Over the past decade, the bismuth price has fluctuated
between US$3 and US$14 per pound
(99.99% bismuth ingots).
Is bismuth a girl?

How do humans use bismuth?
Bismuth finds its main uses in
pharmaceuticals
, atomic fire alarms and sprinkler systems, solders and other alloys and pigments for cosmetics, glass and ceramics. It is also used as a catalyst in rubber production.
Does bismuth break easily?
Bismuth is a soft, silvery metal with a bright, shiny surface and a yellowish or pinkish tinge. The
metal breaks easily
and cannot be fabricated (worked with) at room temperature.
Is bismuth safe to touch?
Unlike lead, mercury, nickel, or other metals,
there is no significant health risk from vapors or from touching bismuth or ingesting small amounts
(it’s actually the active ingredient in a popular brand of stomach medicine).
Is bismuth safe to ingest?
Bismuth is POSSIBLY UNSAFE when taken by mouth
in large amounts or over a prolonged time period. Allergy to salicylate: Many bismuth supplements contain the bismuth salt called bismuth subsalicylate. When taken by mouth, bismuth subsalicylate breaks down in the stomach to form bismuth and salicylate.
Does bismuth lose its color?
What do you mean oxidizing?
Bismuth is stable in air but will turn black in the presence of sulphur
.
