Is antimony shiny or dull?
Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow).
Elemental antimony is a brittle, silver-white shiny metalloid..
Why is Tungsten W?
Tungsten comes from a Swedish term, tung sten, that means “heavy stone.” Tungsten’s chemical symbol is a W, which may seem weird since there isn’t a W in the word. The W actually comes from the element’s other name, wolfram. The name wolfram comes from the mineral the element was discovered in, wolframite.
Is antimony toxic to the body?
Antimony toxicity occurs either due to occupational exposure or during therapy. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans.
Where is Antimony most commonly found?
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.

Which food contains gold?
From chicken wings to chocolate, gold food is becoming a new food trend. Edible gold foods are covered in 24k gold leaf, which is safe to eat but can’t be broken down by your body. In Japan, Gold Kit Kat bars have gotten the Midas touch, and sushi chefs are adding gold topping to make their nigiri sushi sushi pop.
What foods are high in silver?
Silver can even be found as a trace mineral in some of the natural foods we eat, and is a normal constituent of the mammalian diet. We can find these trace amounts of silver in whole grains, fish, mushrooms, and milk from humans, cows and goats.
How much antimony is lethal?
The lethal oral dose of metallic antimony in rats is 100 mg/kg of body weight; the trivalent and pentavalent oxides are less toxic, with LD50 in rats ranging from 3200–4000 mg/kg of body weight. The recommended workplace limit (ACGIH TLV-TWA) for antimony is 0.5 mg/m3 as an 8-hour time-weighted average.
What antimony does to the body?
Antimony in the air can cause lung effects in workers and laboratory animals. Antimony can also cause heart problems. It can damage the heart muscle and cause changes in electrocardiogram (EKG) readings. High levels of antimony in drinking water can cause vomiting and abdominal pain.
Where is arsenic mined?
Arsenic is mined in China, Chile, Russia, Mexico, and the Philippines.
How do you identify antimony?
